Abstract

ABSTRACT In this paper, a disturbance observer is devised for motion control systems suffering unknown periodic disturbances. In the proposed scheme, the structure of a so-called integral disturbance observer is utilized for its error-feedback form, and the repetitive learning control theory is applied to the observer design, constituting an infinite-order integral disturbance observer to obtain an enhanced estimation of a periodic disturbance. A comparative study of different disturbance observers is performed, and experimental results are reported, practically showing the effectiveness of the proposed scheme.
一种用于改进运动控制系统周期扰动估计的无限阶积分扰动观测器
针对运动控制系统中存在未知周期扰动的情况,设计了扰动观测器。在该方案中,利用所谓的积分扰动观测器的结构作为其误差反馈形式,并将重复学习控制理论应用于观测器设计,构成一个无限阶积分扰动观测器,以获得对周期扰动的增强估计。对不同扰动观测器进行了比较研究,并给出了实验结果,实际证明了所提方案的有效性。
