摘要
研究模糊非线性系统在同时具有区域极点、H∞和方差约束下的容错控制器的设计.利用分解和等价原理,将模糊非线性系统多性能指标约束下的可靠控制问题,转换为一系列线性极限子系统的容错控制器的设计问题;利用线性矩阵不等式理论,给出多性能指标约束下的线性系统容错控制器设计方法,分析了相容指标的取值范围,并给出相容指标约束下的容错控制器设计步骤.仿真实例验证了结果的有效性.
Studies the problem of fuzzy fault-tolerant controller design for fuzzy nonlinear systems with regional pole index, steady variance index and H∞ constraints. Based on the decomposition and equivalence principle, the problem of reliable control for fuzzy nonlinear systems is converted to extreme subsystems＇ fault-tolerant controllers design. Through linear matrix inequality theory, a new linear fault-tolerant control system design method is set up, and the range of consistent indices is analyzed in detail. The design step of fault-tolerant controller with multi preformanee indeces constraints is provided. A simulation example showed the efficiency of the design method.
