    Revisiting the simplified IMC tuning rules for low-order controllers: Feedforward controller
    (The Institution of engineering and technology, 2020) Rodríguez, Carlos; Aranda Escolástico, Ernesto; Guzmán, José Luis; Berenguel, Manuel; Hägglund, Tore
    In this work, the load disturbance rejection problem is studied. Specifically, feedforward compensators are considered to reduce the effect of the disturbance in the process’ performance. We propose simple tuning rules that can be easily applied to a wide range of processes improving the response against the disturbance. The improvement of the proposed method is measured through different performance indices in several simulation examples.

    Decoupled feedforward-feedback periodic event-triggered control for disturbance rejection
    (Elsevier, 2021-04-14) Aranda Escolástico, Ernesto; Guinaldo Losada, María; Guzmán, José Luis; Dormido Canto, Sebastián
    In this paper, feedforward and feedback controllers are studied considering decoupled periodic event-triggering mechanisms for output and disturbance sensors. Stability and robustness conditions for linear systems are obtained considering transportation delays and actuator saturation following the Lyapunov-Krasovskii procedure. A numerical example shows that the proposed control strategy reduces the communication between sensors and controller significantly, while the system performance is not deteriorated.

    Revisiting the simplified IMC tuning rules for low-order controllers: Novel 2DoF feedback controller
    (The Institution of Engineering and Technology, 2020) Rodríguez, Carlos; Aranda Escolástico, Ernesto; Guzmán, José Luis; Berenguel, Manuel; Hägglund, Tore
    This paper revisites the direct synthesis tuning method of continuous-time low-order controllers, and specially PID controllers, for control of time-delayed single-input single-output processes. A setpoint prefilter is included to improve the servo response and integrating load disturbances are accounted for. Robustness is addressed by the feedback controller to obtain the desired maximum sensitivity value. Similar results in step disturbance compensation are obtained with simpler analytical tuning rules when compared to recently reported methods. However, the proposed procedure enables to compensate integrating load disturbances, which are not handled in the other methods.
