Control predictor con ponderación de retardos: análisis de prestaciones y robustez ante retardo variable

Abstract : Predictor-based controllers, in particular those obtained by Finite Spectrum Assignment (a.k.a. reduction) method, allow controlling systems with constant and known delays by using an equivalent delay-free model. However, if delay is time-varying or there exist uncertainties in the process model, delay e_ects cannot be exactly compensated. This work proposes a multiple weighted-delay predictor, where the weighting coe_cients are computed by an iterative algorithm. Then, it will be proved that, given a pre-existing controller designed for some delayfree process, the proposed scheme achieves better robustness and performance than single-horizon predictors
