摘要
通过对参数不确定时滞系统的容错控制的研究,针对执行器和传感器的失效故障,利用Riccati方程和Lyapunov稳定性定理,提出一种基于带有时滞项输出反馈控制的鲁棒容错控制器设计方法,并给出各种故障模式下的容错控制条件。仿真结果表明,该方法具有良好的鲁棒容错控制效果。
The robust fault-tolerant control for uncertain time-delay system was considered. A design method of robust fault-tolerant controller against actuator and sensor failures was proposed based on time-delay output feedback using Riccati equation and Lyapunov stability theory. The fault-tolerant control conditions for various failures were given. The simulation results demonstrate that the method has a good robust fault tolerant control capability.
