摘要
本文基于Lyapunov稳定性理论和线性变换技术，研究了离散系统的D稳定容错控制问题，给出了对传感器失效具有完整性的D稳定系统需满足的一个充分条件，进而讨论了不确定离散系统的D稳定鲁棒容错控制问题，并把结果推广到执行器失效的情况，给出了D稳定鲁棒容错控制系统的设计方法．最后用设计实例及仿真结果验证了这种方法的有效性．
In this paper,on the basis of Lyapunov stability theory and linear transformation techniques,the problem of D-stable robust fault-tolerant control for discrete systems is studied. A sufficient condition that D-stable system possessing integrity against sensor failures is given. Then D-stable robust fault-tolerant control problem of uncertain discrete system is discussed,and develop the results to actuator failure case. Design method of D-stable robust fault-tolerant control system is given. Finally,an illustrative example and simulation results are given to demonstrate the effectiveness of the design method proposed in this paper.
