离散时滞系统时滞状态反馈D稳定容错控制

D-stable fault-tolerant control with time-delay state feedback in discrete time-delay systems

针对离散一步时滞系统传感器故障,采用状态反馈和带有时滞的状态反馈控制,给出了一个对传感器失效具有完整性的D稳定控制系统需满足的一个充分条件,进而给出控制器的设计方法和步骤,并推广至执行器失效情况,指出了时滞状态反馈增益矩阵的选取原则.仿真实验验证了该方法的有效性.

Aimed at the sensor failures with single-stepped time delay and using the control with state feedback and time-delay state feedback, a sufficient condition was presented for D-stable control systems possess which would integrity to against sensor failures, then a design method of controller was given, and generalized to the situation of actuator failures. Finally, the choosing principles of gain matrix of time-delay state feedback was given. Simulation results were given to demonstrate the effectiveness of the proposed method.
