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 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 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 A Study of Strategies for Developing Online Laboratories(IEEE, 2021-12-01) Sáenz Valiente, Jacobo; Torre Cubillo, Luis de la; Chacón Sombría, Jesús; Dormido Canto, SebastiánResearchers and teachers around the world have created newsoftware and hardware to develop, reuse, and deploy online laboratories (labs). However, due to the nature of labs, most of the available solutions depend greatly on where and how online labs can be used in the first place. Thus, there have been multiple design solutions and great technology combinations. In this study, we analyzed and studied the main obstacles in the online lab development and the alternatives of the technologies, means, methodologies, and approaches on creating online labs. The resulting analysis showed the advantages, disadvantages, and problems of each key component and attempted to explore the working combinations that ensure the usability, modularity, universality, accessibility, and reliability of online labs. In addition, we explored a general solution to take advantage of the benefits of the technologies involved in online labs and to fix or reduce the impacts of the arising problems when developing and deploying online labs.Publicación The Ball and Beam System: A Case Study of Virtual and Remote Lab Enhancement With Moodle(IEEE (Institute of Electrical and Electronics Engineers), 2015-06-10) Torre Cubillo, Luis de la; Guinaldo Losada, María; Heradio Gil, Rubén; Dormido Canto, SebastiánWeb-based labs are key tools for distance education that help to illustrate scientific phenomena, which require costly or difficult-to-assemble equipment. Easy Java Simulations (EJS) is an authoring tool that speeds up the creation of these kind of labs. An excellent proof of the EJS potential is the open source physics (OSP) repository, which hosts hundreds of free EJS labs. Learning management systems, such as Moodle, provide social contexts where students interact with each other. The work described in this paper looks for the synergy of both tools, EJS and Moodle, by supporting the deployment of EJS labs into Moodle and thus enriching them with social features (e.g., chat, forums, and videoconference). To test this approach, the authors have created the ball and beam lab, which helps students of automatic control engineering to train different advanced techniques (robust, fuzzy, and reset control), and compare their performance in relation to a conventional proportional-integral-derivative control.Publicación Open and Low-Cost Virtual and Remote Labs on Control Engineering(Institute of Electrical and Electronics Engineers, 2015-06-15) Sáenz Valiente, Jacobo; Chacón; Jesús; Torre Cubillo, Luis de la; Antonio Visioli; Dormido Canto, SebastiánThis paper presents an open course in the University Network of Interactive Laboratories, which offers several virtual and remote laboratories on automatic control, accessible to anyone. All the details on one of these labs (a two electric coupled drives system that allows performing control practices in a 2 × 2 MIMO system with industrial applications) and the activities that can be performed with it are given. We use a low-cost solution for developing the virtual and remote labs shared in this open course, based on the use of a free authoring tool Easy Java/Javascript Simulations (EJsS) for building the laboratories' user interfaces and a cheap development platform board (BeagleBone Black). The virtual and remote labs are deployed into a free Learning Management System (Moodle) Web environment that facilitates their management and maintenance.Publicación The photoelectric effect and study of the diffraction of light: Two new experiments in UNILabs virtual and remote laboratories network(Società Italiana di Fisica, 2016-02-12) Sánchez Fernández, Juan Pedro; Sáenz Valiente, Jacobo; Torre Cubillo, Luis de la; Carreras, Carmen; Yuste, Manuel; Heradio Gil, Rubén; Dormido Canto, SebastiánThis work describes two experiments: “study of the diffraction of light: Fraunhofer approximation” and “the photoelectric effect”. Both of them count with a virtual, simulated, version of the experiment as well as with a real one which can be operated remotely. The two previous virtual and remote labs (built using Easy Java(script) Simulations) are integrated in UNILabs, a network of online interactive laboratories based on the free Learning Management System Moodle. In this web environment, students can find not only the virtual and remote labs but also manuals with related theory, the user interface description for each application, and so on.Publicación Virtual and Remote Labs in Control Education: a Survey(Elsevier, 2016-11-14) Heradio Gil, Rubén; Torre Cubillo, Luis de la; Dormido Canto, SebastiánVirtual and remote labs have been around for almost twenty years and while they have been constantly gaining popularity since their appearance, there are still many people in the control education community who either do not know many details about them or do not know them at all. What are their benefits? Which examples of virtual and remote labs for control education can be found in the Internet and how spread and popular are they? What are the current trends and issues in the implementation and deployment of these tools? And the future ones? These and others are some of the questions we answer in this paper, trying to bring the attention of the control education community to these tools which, we believe, are meant to have an increasing importance and relevance for the 21st century students.Publicación What remote labs can do for you(AIP Publishing, 2016-04-01) Torre Cubillo, Luis de la; Sánchez Fernández, Juan Pedro; Dormido Canto, SebastiánThe Internet of Things (IoT) is the network of physical devices connected to the internet. Online connections enable users to remotely monitor the devices and their surroundings or to actively control them through sensors and actuators. As the technology has progressed, the importance of the IoT has grown tremendously. According to the McKinsey Global Institute, the IoT’s annual economic impact could reach $11 trillion by 2025. That figure represents about 10% of today’s world economy.1 Bullish sounding at first, the prediction is not so ridiculous if one stops to think about how deeply internet technologies have already penetrated today’s society. Consider, for example, mobile devices—those smartphones and tablets everybody carries nowadays. A typical modern smartphone has numerous sensors that allow it to capture the device’s orientation, location, ambient light conditions, and much more. And it is frequently connected to the internet. A world filled with such internet-connected devices opens...Publicación Adding automatic evaluation to interactive virtual labs(Taylor and Francis Group, 2015-04-07) Farias, Gonzalo; David Muñoz de la Peña; Fabio Gómez-Estern; Torre Cubillo, Luis de la; Gómez Sánchez, Carlos; Dormido Canto, SebastiánAutomatic evaluation is a challenging field that has been addressed by the academic community in order to reduce the assessment workload. In this work we present a new element for the authoring tool Easy Java Simulations (EJS). This element, which is named automatic evaluation element (AEE), provides automatic evaluation to virtual and remote laboratories built with EJS by using the server application Goodle grading management system (GMS). The integration of both tools entitles a professor to create interactive virtual and remote laboratories and automatically evaluate the work of their students. As a test bed two case studies are presented; a non-linear controller design virtual laboratory used in an advanced control master course and a servomechanism virtual laboratory used in an undergraduate basic control course.
