    Asynchronous periodic event-triggered control with dynamical controllers
    (Elsevier, 2018-04-20) Aranda Escolástico, Ernesto; Rodríguez, Carlos; Guinaldo Losada, María; Guzmán, José Luis; Dormido Canto, Sebastián
    In this work, we study a networked control system under a periodic eventtriggered control strategy. In addition, the input and the output of the system are sampled with different rates, which enables to obtain a compromise between performance and waste of communication resources. Stability analysis and L2-gain analysis are carried out through Lyapunov-Krasovskii techniques. Simulation results of a quadruple-tank process show the benefits of the approach.

    Event–Based Feedforward Control of Linear Systems with input Time–Delay
    (Sciendo, 2019-09-28) Rodríguez, Carlos; Aranda Escolástico, Ernesto; Guinaldo Losada, María; Guzmán, José Luis; Dormido Canto, Sebastián
    This paper proposes a new method for the analysis of continuous and periodic event-based state-feedback plus static feedforward controllers that regulate linear time invariant systems with time delays. Measurable disturbances are used in both control law and triggering condition to provide better disturbance attenuation. Asymptotic stability and L2-gain disturbance rejection problems are addressed by means of Lyapunov-Krasovskii functionals leading to performance conditions that are expressed in terms of linear matrix inequalities. The proposed controller obtains better disturbance rejection and a reduction in the number of transmissions with respect to other robust event-triggered controllers in the literature.

    An Object-Oriented Library for Process Control Simulations in MATLAB
    (ELSEVIER, 2017) Rodríguez, Carlos; Guinaldo Losada, María; Aranda Escolástico, Ernesto; Guzmán, José L.
    This paper presents a library of MATLAB classes developed to provide a framework to allow performing easy and scalable process control simulations. The proposed object-oriented tool features the basic components of a control loop including: processes, controllers, sensors, actuators and connection links. The simulator can be configured to carry out simulations with continuous and/or discrete elements, and/or include event-triggered capabilities in a straightforward manner. The benefits of the proposed library are shown with the rapid development and simulation of a quadruple-tank system that is controlled by means of a PI controller.
