摘要
提出一种干扰解耦观测器设计的新方法。首先指出 :测量中的未知输入作用可以通过简单的代数变换而消除 ;然后利用类似的变换 ,提出测量中不含未知输入时干扰解耦观测器设计的新方法 ,并得到干扰解耦观测器存在的充要条件。新的设计方法直观简单 ,便于推广应用。设计实例说明了其有效性。
A novel disturbance decoupled observer (DDO) design scheme is presented. It is firstly pointed out that unknown input appearing in measurement can be eliminated by a simple algebraic transformation. Then, a new DDO design scheme is proposed via a similar transformation when unknown input does not appear in measurement. The necessary and sufficient conditions for the existence of DDO are presented. The design procedure proposed is simple and straightforward enough to be applied. An example is given to show its efficiency.
