A fault tolerant control framework for periodic switched non-linear systems. (English)
[J] Int. J. Control 82, No. 1, 117-129 (2009). ISSN 0020-7179; ISSN 1366-5820/e

Summary: An observer-based fault tolerant control (FTC) framework is proposed for a class of periodic switched non-linear systems (PSNS) without full state measurements. Two kinds of faults are considered: continuous faults that affect each mode during its dwell period; and discrete faults that affect the switching sequence. Under the average dwell time scheme, the proposed FTC framework can maintain the stability of overall PSNS in spite of these two kinds of fault. A switched reluctance motor example is taken to illustrate the efficiency of the proposed method.
