线性广义系统的容错控制器设计

Design of Fault-tolerant Controller to Linear Descriptor Systems

针对执行器失效的线性时不变广义系统 ,利用Riccati不等式给出具有执行器完整性控制器的设计方法 ,所设计的状态反馈控制器在系统正常时是D -允许的 ,在一定条件下 ,仍能使执行器故障具有D -允许的 .

Based on Riccati inequality, a designing method of controller for descriptor system with actuator failure is presented. The induced system possesses integrity against actuator failure. The designed state feedback controller is D admissible. Under certain condition the same control law guarantees the system's D admissible.
