摘　　要：利用高速磁浮列车搭接结构的冗余机制,采用有理函数稳定因式分解的方法,设计了一种针对典型开环不稳定线性系统的被动容错控制器。利用经典极点配置方法搜索同时镇定问题的解,具体设计了不需繁琐的公式推导和复杂的控制器设计算法。仿真表明,在搭接结构中一个电磁铁组完全失效的情况下,该控制器仍然能够实现搭接结构稳定悬浮。试验结果表明,该控制器对被控对象的参数特性变化具有鲁棒性,对系统故障具有稳定意义上的容错能力。Considering the iuherent redundancy of joint structure of high speed maglev train, a passive fault-tolerant controller is designed for the linear unstable open-loop system by adopting a method of factorization of stable rational function. The solution to the stabilization problem is searched by the technique of eigenvalues assignment, and the synthesis can usually be achieved without fussy formula deduction and complex computer algorithms. The simulations indicate that the controller can suspend the joint structure stable when a failure of the other electromagnet occars.The results show that the controller has the robustness to the parameter variation of the controlled object and the fault-tolerance property of stabilization.
