    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, Sebastián
    This 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.

    A relay-feedback automatic tuning methodology of PIDA controllers for high-order processes
    (Taylor & Francis, 2024) Antonio Visioli; Sánchez Moreno, José
    In this paper, we present a new automatic tuning methodology for proportional-integral-derivative-acceleration controllers. In particular, a (possibly high-order) model of the process is obtained by means of a relay-feedback test. Then, the four parameters of the controller are determined by approximating the general feedback internal model controller with a truncated Maclaurin series. In this context, the user can select a parameter that determines the speed of the response of the closed-loop system and implicitly handles the trade-off between aggressiveness and robustness. It is shown that the additional acceleration action allows an improvement of the performance with respect to a traditional proportional-integral-derivative controller and represents an effective solution for the control of high-order systems.
