Publicación An event-based adaptation of the relay feedback experiment for frequency response identification of stable processes(Elsevier, 2023-04-13) Sánchez Moreno, José; Torre Cubillo, Luis de la; Chacón Sombría, Jesús; Dormido Canto, Sebastián; Elsevier; https://orcid.org/0000-0003-0898-3462An event-based modification of the classical relay feedback experiment without the inclusion of additional elements (integrator, time delay, . . . ) for identification of the spectrum of stable processes between zero and the phase cross-over frequency is presented. By inserting an event-based sampler in the control loop, the natural behaviour of a classical relay is simulated and the system is forced to work in two modes. The event-based sampler activates the first mode by sending control actions to the process every time the error signal crosses zero; this mode is to discover the approximated value of the cross-over frequency ω180◦ . During the second mode, the event-based sampler sends samples to the process simulating that the error signal crosses zero at ω180◦ /N where N is the number of points to identify in the range 0 ≤ ω ≤ ω180◦ . One advantage of this procedure is that the logic used in an already existing relay feedback experiment to fit a transfer function model or tune a controller could be maintained just replacing the relay block by the event-based sampler block presented in the paper. Simulations and experiments with different processes and in presence of noise demonstrate the effectivity of the procedure.Publicación Exemplar driven development of software product lines(Elsevier, 2012-12-01) Heradio Gil, Rubén; Fernández Amoros, David José; Torre Cubillo, Luis de la; Abad Cardiel, IsmaelThe benefits of following a product line approach to develop similar software systems are well documented. Nevertheless, some case studies have revealed significant barriers to adopt such approach. In order to minimize the paradigm shift between conventional software engineering and software product line engineering, this paper presents a new development process where the products of a domain are made by analogy to an existing product. Furthermore, this paper discusses the capabilities and limitations of different techniques to implement the analogy relation and proposes a new language to overcome such limitations.Publicación Automatic Generation and Easy Deployment of Digitized Laboratories(IEEE, 2020-12-01) Torre Cubillo, Luis de la; Neustock, Lars Thorben; Herring, George K.; Chacon, Jesus; García Clemente, Félix J.; Hesselink, LambertusThis article presents a general way to enable automatic generation of digitized laboratories (a sort of digital twin for laboratory experimental setups) from remote laboratories and their easy deployment and publication. To demonstrate its effectiveness, we use two existing tools to generate and publish two digitized laboratories online from two implementations of a Snell's law remote laboratory, although they could be applied to many other remote laboratories. The first of these tools is a communication protocol that was designed to manipulate laboratory equipment through the Internet. This protocol can be used to automatically loop through different possible laboratory states and store them. The second one is a web platform that allows uploading files, that contain data sets of the laboratory states, to publish the digitized laboratory as a web application that is generated automatically.Publicación Secure and Private Internet of Things for Industry, Training, and Homes: A Communications Solution for Connected Devices(IEEE, 2023-09-01) Sánchez Herrera, María Reyes; Márquez, Marco; Torre Cubillo, Luis de laWe are currently living in the era of the Internet of Things (IoT) [1], which has been fostered by the electronic and communications revolution that happened in recent decades. The already great number of devices connected is continuously increasing, while their size and energy consumption keep decreasing. These IoT devices offer network interfaces that allow the interaction between a user/manager and the device through the network. These interfaces are usually developed by the manufacturers, and so, they constitute a private software interface (PSI). Within the IoT, a great variety of devices, such as, for example, appliances and other electric equipment, are publicly accessed. The essence of the IoT’s structure is presented in Figure 1, where appliances are accessible through a smartphone and their local area network (LAN). This basic architecture has been used in older IoT works such as [2]. To get this accessibility, the user must first register in a cloud, which is usually run by the manufacturer of the appliance, meaning that the management of the data is completely unknown for the end user in most cases. This lack of privacy does not dissuade people from using those devices (in many cases, because the only alternative is to not use such a device at all), but also, nowadays, people manage a large part of their professional, personal, and leisure information through the Internet [3], within a cloud (cloud computing) [4].Publicación II Jornada de innovación y tecnologías educativas en la ETSI de informática(Universidad Nacional de Educación a Distancia (España). Editorial, 2016-11) Rodríquez Artacho, Miguel; Martínez Tomás, Rafael; Fernández Vindel, José Luis; Letón Molina, Emilio; Pérez de Madrid y Pablo, Ángel; Torre Cubillo, Luis de laLa jornada estaba motivada por la pregunta: "¿Cómo hacemos uso de la innovación educativa y de los medios tecnológicos para mejorar la efectividad de nuestra docencia y la experiencia de usuario de nuestros estudiantes?".Publicación WarehouseGame Training: A Gamified Logistics Training Platform Integrating ChatGPT, DeepSeek, and Grok for Adaptive Learning(MDPI, 2025-06-06) Romero Marras, Juan José; Torre Cubillo, Luis de la; Chaos García, DictinoModern warehouses play a fundamental role in today’s logistics, serving as strategic hubs for the reception, storage, and distribution of goods. However, training warehouse operators presents a significant challenge due to the complexity of logistics processes and the need for efficient and engaging learning methods. Training in logistics operations requires practical experience and the ability to adapt to real-world scenarios, which can result in high training costs. In this context, gamification and artificial intelligence emerge as innovative solutions to enhance training by increasing operator motivation, reducing learning time, and optimizing costs through personalized approaches. But is it possible to effectively apply these techniques to logistics training? This study introduces WarehouseGame Training, a gamified training tool developed in collaboration with Mecalux Software Solutions and implemented in Unity 3D. The solution integrates large language models (LLMs) such as ChatGPT, DeepSeek, and Grok to enhance adaptive learning. These models dynamically adjust challenge difficulty, provide contextual assistance, and evaluate user performance in logistics training scenarios. Through this gamified training tool, the performance of these AI models is analyzed and compared, assessing their ability to improve the learning experience and determine which one best adapts to this type of training.Publicación Evidence-Based Control Engineering Education: Evaluating the LCSD Simulation Tool(IEEE, 2020-09-25) Marin, Loreto; Vargas, Héctor; Heradio Gil, Rubén; Torre Cubillo, Luis de la; Díaz Martínez, José Manuel; Dormido Canto, SebastiánThe advance in control engineering education needs well-designed studies that validate what methods and tools work best. This paper addresses the lack of empirical evidence supporting innovations in control engineering education by proposing a methodology that works at different abstraction levels. Hence, innovations' impact on students' performance can be statistically analyzed either globally or locally by examining competencies or fine-grained indicators, respectively. The article reports the application of the methodology for evaluating an interactive simulation tool, named LCSD, on 101 students at the Pontifical Catholic University of Valparaiso in Chile. According to the experimental results, LCSD is an effective free alternative to enhance the student's skills on control system analysis for our automatic control course. Also, some improvements have been identified for future LCSD versions.Publicación Scalable Hybrid Laboratories: Application in Industrial Automation(ELSEVIER, 2025-05-27) Vilches, Marco; Vargas, Héctor; Torre Cubillo, Luis de la; Heradio Gil, RubénSome of the most critical competencies that automation and control students must acquire to become capable engineers require hands-on laboratory expe- riences under conditions that closely resemble real-world work environments. However, current practical laboratories often face challenges in recreating re- alistic and scalable industrial contexts, making it difficult to develop these competencies. This article presents the development and implementation of a hybrid laboratory proposal to address these challenges. The prototype, de- signed for training automation engineers, integrates real control devices with simulated digital replicas of processes, allowing the scalability of the system to address a wide variety of industry-like scenarios. The general design, its physical and virtual implementation, the communication of its components, and the installation and operation context are detailed. The article concludes with the potential advantages and benefits of the hybrid laboratory from an academic teaching perspective, the training of industry professionals, and the technical optimization of the engineering problem addressed.Publicación Control education for societal-scale challenges: A community roadmap(ELSEVIER, 2023-03-17) Rossiter, John Anthony; Cassandras, Christos G.; Hespanha, João; Dormido Canto, Sebastián; Torre Cubillo, Luis de la; Ranade, Gireeja; Visioli, Antonio; Hedengren, John; Murray, Richard M.; Antsaklis, Panos; Lamnabhi Lagarrigue, Francoise; Parisini, ThomasThis article focuses on extending, disseminating and interpreting the findings of an IEEE Control Systems Society working group looking at the role of control theory and engineering in solving some of the many current and future societal challenges. The findings are interpreted in a manner designed to give focus and direction to both future education and research work in the general control theory and engineering arena, interpreted in the broadest sense. The paper is intended to promote discussion in the community and also provide a useful starting point for colleagues wishing to re-imagine the design and delivery of control-related topics in our education systems, especially at the tertiary level and beyond.Publicación New generation virtual and remote laboratories : integration into web environments 2.0 with learning management systems(Universidad Nacional de Educación a Distancia (España). Escuela Técnica Superior de Ingeniería Informática. Departamento de Informática y Automática, 2013-06-27) Torre Cubillo, Luis de la; Sánchez Moreno, José; Dormido Bencomo, SebastiánLearning Management Systems (LMS) are software for web applications oriented for the administration, documentation, tracking, and reporting of e-learning programs. Moodle is a free source LMS with more than 63 million users, which makes it the most used LMS around the world. Like some other LMS, the stated philosophy of Moodle includes a constructivist and social constructionist approach to education, emphasizing that learners (and not just teachers) can contribute to the educational experience. This is the web 2.0 applied to education. Easy Java Simulations (EJS) is an authoring tool written in Java that helps to create interactive simulations in Java, mainly for teaching and learning purposes. By means of this tool, instructors can easily create virtual and/or (if they also use the appropriate additional software) remote laboratories. While virtual laboratories are based on mathematical models, remote ones use real equipment and so, the experiments are carried out in the reality. Virtual and remote laboratories (created with EJS, for example) as well as LMS (Moodle, for example) offer different but fundamental educational tools to both teachers and students. Since these resources are complementary (and not mutually exclusive), e-learning programs should offer both kinds of tools to be considered a complete experience for students. However, the integration between these two different resources is still an open issue that must be addressed. This thesis gathers together the two previous resources and provides the necessary tools and methodology for developing web experimentation portals (such as UNEDLabs, also presented here) that can offer e-learning programs based on: 1) experimentation (thanks to the use of the virtual and remote laboratories) and 2) theory documentation provision, social interactivity and easy management (thanks to the use of a LMS). Moreover, the presented tools and methodology allow people not specialized in these particular topics (such as they are the vast majority of the teachers) to easily create these kind of experimentation portals and populate them with virtual and/or remote laboratories (VRLs). Four new Moodle plug-ins facilitate this task: EJSApp, EJSApp Booking System, EJSApp Files Browser and EJSApp Collab Sessions. Nowadays, UNEDLabs holds two courses (among others); one in Control Engineering and another one in Physics. Both of them offer three experiments which are all available in the two possible versions: virtual and remote. The Physics course is still growing and new experiments are added every year. Right now, the three available ones are a motorized rotatory laser for studying the light in isotropic media, a motorized optical bench for determining the focal length of a thin lens, and an experiment with three springs and related to Hookes law. Thanks to the tools presented in this work, not only all the EJS laboratories in UNEDLabs are added and integrated into the Moodle web portal in a very easy and natural way, but they also acquire several special functionalities they lack when they are used outside this LMS. The first of these functionalities is the capability of saving and/or loading files to/from the private files repository in Moodle. The second one is the possibility to create collaborative experimental sessions with other users of Moodle who are enrolled to the course the EJS lab belongs to. The third one is an automatic integration with a booking system specifically designed for managing users access to the remote laboratories. Finally, EJS labs in Moodle can be administrated exactly in the same way as any other Moodle resource or activity, meaning they can be updated or deleted; their access can be restricted to a certain group of users or to users that have previously fulfilled some steps or conditions; security copies are automatically performed during Moodles system backups, etc.
