Design of fauslt-tolerant controller via eigenstructure assignment

利用状态反馈特征结构配置参数化结果,给出了设计容错控制器的参数化方法。该方法给出了故障系统的所有容错控制器的参数化表达式。该参数化表达式含有的自由参量为控制系统设计提供了全部自由度,可用来满足控制系统设计的某些性能,如鲁棒性。数值算例及其仿真验证了本文所提容错控制器设计的参数化方法的有效性。

Based on the parametric results of state feedback eigenstructure assignment, a parametric method to design the fault-tolerant controller is proposed. This proposed method presents the parametric expressions of all the fault-tolerant controllers for the fault control system. The free parametric vectors in the parametric expressions offer all the design degrees of freedom, which can be further utilized to satisfy certain specifications in control system designs, such as robustness etc. An illustrative example and the simulation figures show the effect of the proposed algorithm.
