Abstract：his paper presents a high-accuracy H∞ robust position controller for linear permanent magnet synchronous servo motor (LPMSM). We use H∞ control theory to design a feedback controller so as to restrain the model perturbance and the external disturbance on the premise of guaranteeing stability of the closed-loop system. And we design a IP controller based on nominal model of the plant so as to meet the position system′s performance requirement. The designed controller not only guarantees system′s robustness but also system′s following performance. The results of simulation show that the controller presented is reasonable and effective.
