摘要

本文提出了一种离散线性系统扰动观测器的设计方法。为了估计未知扰动，假设估计的扰动为辅助状态变量，构造增广模型。利用线性矩阵不等式(LMI)给出了鲁棒观测器存在和收敛的充分条件。数值算例表明了该方法的有效性。

Design of a disturbance observer for discrete-time linear systems

This paper presents a design method of a disturbance observer for discrete-time linear systems. In order to estimate the unknown disturbance, an augmented model is constructed by supposing the estimated disturbance to be an auxiliary state variable. The sufficient condition for the existence and convergence of the robust observer is proposed in terms of linear matrix inequality (LMI). Numerical examples are given to show the effectiveness of the proposed method.
