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 .该方法直接利用系统的I/O数据估计系统内部状态 ,无需对系统状态有个初始估计 ,相应的也就可以不受初始估计误差的影响 .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 .
Because the deadbeat observer has the property of nilpotent nil at the origin, this paper makes full use of this property and proposes a new deadbeat observer design method for discrete linear systems. This method directly uses the system I / O data to estimate The internal state of the system does not need to have an initial estimate of the state of the system and the corresponding estimate can be unaffected by the initial estimation error.The concrete implementation steps of the observer are given in the paper and the correctness of the proposed method is verified by simulation Effectiveness.
