Fault recoverability analysis of switched systems

Abstract

This article provides an approach to evaluate the fault recoverability of switched systems (SS) under given energetic constraints. Such evaluation reveals the capability of the SS to tolerate the worst faults over a prescribed set under possible energy constraints. The evaluation is achieved by using the smallest eigenvalue of a proposed ‘switched-system controllability Gramian’. Simulation results about a longitudinal flight control process example are presented to show the effectiveness of the proposed method.
