A fault tolerant framework for periodic switched nonlinear systems
Résumé
An observer-based fault tolerant control (FTC) framework is proposed for a class of periodic switched nonlinear systems (PSNS) without full state measurements. Two kinds of faults are considered for PSNS: Continuous faults that affect each mode during its dwell time period; Discrete faults that affect the switching sequence. The proposed FTC framework can maintain the stability of overall PSNS in spite of these two kinds of faults. An illustrative example is given to show the efficiency of the proposed method.
