具有小滞后的连续控制系统的容错控制器设计

研究了小滞后线性连续控制系统的容错控制问题，证明了通过适当选取Ｒｉｃｃａｔｉ方程中的权矩阵Ｑ和Ｒ，当小时滞满足一个不等式时，含有执行器或传感器故障的系统模型的闭环系统为渐进稳定的。给出了系统的容错控制器的设计方法。并用一个例子说明了该方法的有效性。

Fault-tolerant Controller Design for Linear Continuous Control Systems with a Small Time-delay

The fault-tolerant control problem for linear continuous control systems with asmall time-delay is studied. It is proved that if the small time-delay satisfies an ineuqality,theclosed-loop system stability can be maintained in the presence of actuator failures or sensorfailures by properly selecting the weighting matrices Q and R of Riccati euqation, Designmethods of fault-tolerant controller are preseted.An example is given to demonstrate the ef-fectness of proposed method.
