Switching fault tolerant control design via global dissipativity

Abstract

This article addresses the issue of fault tolerant control (FTC) from energy point of view for general impulsive systems with faults ranging over a finite cover. The dissipativity theory is introduced into the design of fault detection and a unique scheme that simultaneously performs fault isolation and FTC. The proposed framework relies on a simple dissipativity-based switching among a family of pre-computed candidate controllers without any additional model or filter. The states are ensured to be bounded during the switching delay. A RLC circuit example illustrates the efficiency of the proposed method.
