摘要
观测器控制系统中的观测器条件是系统的状态观测值渐近收敛于系统真实状态的根本条件。本文首先提出了Luenberger观测器设计的一种参数方法,然后根据使观测器条件误差为最小的准则,考虑了具有参数摄动的系统的鲁棒Luenberger观测器设计问题,给出了简单、有效的算法。仿真结果说明了本文方法的有效性。
The observer condition in the observer-state feedback control system is an essential condition for the observed states to asymptotically approach the real states. In this paper, a parametric approach for the design of Luenberger observer is proposed, and the problem of robust Luenberger observer design for systems with parameter perturbations is then considered based on the criterion of minimum observer condition error. A simple and effective algorithm is given. Simulation results show the effectiveness and application value of the proposed approach.
