| Abstract: | This paper addresses the problem of fuzzy fault-tolerant controller design for fuzzy discrete-time systems with pole index, steady variance index and H∞ constraints. Based on the decomposition and equivalence principle, the reliable control problem for fuzzy nonlinear systems is decomposed into a set of extreme sub-systems fault-tolerant control problems. A new fault-tolerant control design method is proposed, and the range of consistent indices is analyzed in detail. Finally, the design steps of fault-tolerant controller with multi preformance indeces constraints are provided. |
