Supervisory fault tolerant control design via switched system approach

Abstract

This paper focuses on the supervisory fault tolerant control design for a class of nonlinear systems with faults ranging over a finite cover. The proposed framework is based on switched system approach, and relies on a supervisory switching among a family of pre-computed candidate controllers without any additional model. Each faults set can be accommodated by a set of controllers under an appropriate switching law rather than any individual controller. A numerical example illustrates the efficiency of the proposed method.
