摘　　要：传统的永磁同步电机矢量控制性能容易受到电机参数变化的影响,从而产生速度变化超调量不良的结果.本文提出一种将滑模控制器应用到矢量控制中的方法,可有效解决速度超调量大的问题.首先建立永磁同步电机的数学模型,在矢量控制的基础上,结合电机转速和电流的变化,推导出使用指数趋近律来消除抖振的滑模控制器.然后利用SVPWM代替传统的开关表进行逆变控制,并使用MATLAB搭建滑模控制器结合矢量控制的永磁同步电机模型.最后通过改进后的系统与传统矢量控制系统进行对比,确定滑模控制器的优越性.结果表明,滑模控制器结合矢量控制方法下的永磁同步电机的抗干扰能力得到了有效的控制,超调问题也得到了有效的改善,证明了滑模控制器的永磁同步电机矢量控制的有效性.The vector control performance of traditional permanent magnet synchronous motor is easy to be affected by the change of motor parameters,which results in the poor overshoot of speed change.This paper presents a method of applying sliding mode controller to vector control,which can effectively solve the problem of large velocity overshoot.Firstly,a mathematical model of permanent magnet synchronous motor is established.Based on vector control,a sliding mode controller which uses exponential reaching law to eliminate buffeting is derived by combining the change of motor speed and current.Then,SVPWM is used to replace the traditional switch table for inverter control,and MATLAB is used to build a permanent magnet synchronous motor model combining sliding mode controller with vector control.Finally,the superiority of sliding mode controller is determined by comparing the improved system with the traditional vector control system.The results show that the anti-interference ability of PMSM combined with the vector control method is effectively controlled,and the overshoot problem is effectively improved,which proves the effectiveness of the vector control of PMSM by the sliding mode controller.
