Delta算子系统D稳定容错控制

D-stable Fault-tolerant Control for Delta Operator Systems

研究了Delta算子描述的线性系统基于圆形区域极点配置的容错控制问题.分别利用矩阵奇异值和代数Riccati方程给出了该系统利用状态反馈实现D稳定容错控制的两个充分条件,进而给出了D稳定容错控制器的设计方法,将连续与离散系统的有关结果统一到了Delta算子框架中.

The problem of fault-tolerant control for delta operator systems based on regional pole assignment is studied. Sufficient conditions that the poles of the closed-loop system are placed in a specific circular region and the system possessing integrity against actuator failure are presented by means of singular values and algebraic Riccati equations. And the design methods of fault-tolerant control for the delta operator system based on regional pole assignment are developed. The proposed method can unify some related results of continuous and discrete time systems into the delta framework.
