An´alisis y control para sistemas lineales con retardo de tiempo: aplicaci´on a sistemas con reciclo

Abstract

This work presents new results on the observer-controller design for linear timeinvariant plants that may contain times delay. The analysis mainly considers recycling systems. The main contribution described here is the obtained existence conditions of an observer for the systems previously mentioned; results related with step tracking reference as well as step rejecting disturbance are also given. The control schemas developed in this work achieve stability and various performance specifications. Analysis of robustness with respect to time-delay and parameters is provided for some proposed control strategies. In all cases, numerical simulations are presented in order to show the effectiveness of the proposed methodologies
