容错降维观测器设计及其应用

Design and application of observer with fault tolerance and dimension reduction capability

针对系统的不可靠输出 ,提出了一种新的降维观测器设计方法 .该方法对系统输出不可靠具有容错能力 ,并且当输出正常后能够恢复对系统状态变量的跟踪 .

For the unreliabe output from a system, a new approach of designing an observer with fault tolerance and dimension reduction capability is proposed, which can track the variables of the system when the output goes back to normal. Simulations run with a missile attitude control system proved the validity and feasibility of this new approach.
