    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, Ismael
    The 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.

    Using IoT-Type Metadata and Smart Web Design to Create User Interfaces Automatically
    (Institute of Electrical and Electronics Engineers (IEEE), 2023-02) Chacón, Jesús; Chandramouli, Rajarathnam; Torre Cubillo, Luis de la; Chaos García, Dictino; Heradio Gil, Rubén
    The advent of the Internet of Things has generated loads of data from the devices that are now connected to the Internet. While the majority of the data corresponds to measurements done by these devices, there is a second type of information (the metadata) that provides information about the devices themselves. Most of this metadata is still underused when used at all. On the other hand, the graphical user interfaces that allow operating and/or monitoring the connected devices from a computer or smartphone, are usually programmed from zero. However, the metadata that describes the main properties of the devices (i.e., inputs, outputs, precision, range, etc.) can be used along with smart web design techniques to automatically create these interfaces. This article proposes a framework to achieve this, and presents an application example consisting of an online lab of a servo-motor.

    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/0000-0003-0898-3462
    An 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.

    Customized Online Laboratory Experiments: A General Tool and Its Application to the Furuta Inverted Pendulum [Focus on Education]
    (Institute of Electrical and Electronics Engineers (IEEE), 2019-09-17) Galán, Daniel; Chaos García, Dictino; Torre Cubillo, Luis de la; Aranda Escolástico, Ernesto; Heradio Gil, Rubén
    Because of online laboratories (labs), students can perform experimental activities from their mobile devices and/or computers. This article proposes an experimentation environment (EE) that extends the capabilities of interactive online labs with scripting language support. Thus, control engineering students can specify complex experiments, avoid routine tasks, and empirically test controllers they made themselves.
