Abstract

This paper presents a method for designing switching rules that drive the state of a class of nonlinear switched system to a desired constant reference. The proposed method is focused on an application of a three-phase squirrel-cage induction motor fed by an inverter and considers a switching rule using ´max´ composition of auxiliary functions. The results are given in terms of linear matrix inequalities and they guarantee local asymptotic stability of the closed-loop system even if sliding modes occur on any switching surface of the system.
