Deadbeat观测器的一种新的设计方法及实现

ｄｅａｄｂｅａｔ观测器由于极点在原点而具有系统阵幂零的性质，本文充分利用这一性质，针对离散线性系统，提出了一种新的ｄｅａｄｂｅａｔ观测器设计方法，该方法直接利用的Ｉ／Ｏ数据估计系统内部状态，无需对系统状态有个寝估计，相应的也就可以不受寝估计误差的影响，文中给出了该观测器的具体实现步骤，并通过仿真验证了所提出方法的正确性与有效性。

A New Design Method of Deadbeat Observer and Its Implementation

Because all poles of a deadbeat observer are at the origin of coordinates, it has the character that the power of system matrix equals zero. Based on this character, we put forward a new method to design deadbeat observer for discrete linear systems in this paper. We can directly construct a deadbeat observer from I/O data without applying the technique of pole assignment. We give a detailed implementation procedure of the deadbeat observer. The correctness and validity is tested by simulation.
