摘要
针对多变量反馈系统,基于参数空间设计的思想以及“n-线性特征系数”系统理论,提出了一种新的、对执行器与传感器故障的容错控制方法。它是通过保证在正常及各种故障模式下系统的极点均处在s平面上某个可行区域之中,即容错极点配置而实现的。讨论了参数空间设计的基本过程,给出了容错状态及输出反馈控制律的设计方法。
A new design method is proposed for multivariable system to realize the faulttolerant control against its actuator and sensor failure based on the concept of parameter space design. Such fault-tolerance results from locating the poles of the system in a prescribed region on the s-plane under each failure mode, i. e. the fault-tolerant pole assignment. Thedesign method for a fixed state or output feedback law which results in fault-tolerance is given out with the parameter space design procedure being briefly introduced.
