摘　　要：介绍了船舶永磁同步电动机(PMSM)的直接转矩控制(DTC)原理和设计方法.为了克服低速时常规DTC系统存在的磁链和转矩脉动较大、难以控制等问题,引入了滑模变结构控制算法.基于MATLAB平台,建立了具有滑模变结构功能的直接转矩控制系统仿真模型,实验结果表明该算法可改善原系统的动、静态性能,对系统参数和外部干扰表现出较强的鲁棒性.This paper designs a control strategy that Direct Torque Control（DTC） for ship Permanent Magnet Synchronous Motor（PMSM）.In order to overcome those problems conventional DTC system possess,such as flux and torque ripple and difficult to control,a sliding mode variable structure control algorithm is proposed.Based on MATLAB platform,it is established that sliding mode variable structure function of direct torque control system simulation model,the experimental results show that the proposed algorithm can improve dynamic and static performance of the system,at the same time it represents strong robustness that parameters and external disturbance of the system.
