Set-point stabilization of SISO linear systems using first order reset elements

Abstract

In this paper we further develop on a novel representation of First Order Reset Elements (FORE) control systems for SISO plants. We study here the problem of guaranteeing asymptotic tracking of constant references for general plants, which may or may not contain an integrator (namely, an internal model of the constant reference signal). We propose a generalization of the FORE which allows to guarantee asymptotic tracking of constant references when the plant parameters are perfectly known. Robustness of the scheme follows from the ∞ stability properties of the FORE control schemes. The proposed approach is successfully illustrated on a simulation example. ©2007 IEEE.
