摘要
永磁同步直线电机以其直驱,大推力,高精度定位的特点在现代工业领域得到了广泛应用。相较传统旋转电机,省去了运动转换机构,提高了运行效率和执行精度。但由于直线电机的端部效应,运行过程中电感参数易变等问题,仍然需要在结构和控制算法上不断改进,所以对其控制方法的研究仍是当今的研究热点。本文中利用积分滑模控制算法完成对于直线电机的速度控制,并采用差分进化算法来优化运行过程的控制参数,从而提高直线电机的运动稳定性和抗干扰能力。
Permanent magnet synchronous linear motors have been widely used in modern industrial fields due to their direct drive,high thrust and high precision positioning.Compared with the traditional rotating electric machine,the motion conversion mechanism is omitted,and the operating efficiency and the execution precision are improved.However,the permanent magnet synchronous linear motor has an edge effect,and its air gap magnetic field is not completely closed,it is still necessary to continuously improve the structure and control algorithm.Therefore,the research on its control method is still a research hotspot.In this paper,the integral sliding mode control algorithm is used to complete the speed control of the linear motor,and The differential evolution algorithm is used to select the parameters of the controller to improve the operation process,thereby improving the motion stability and anti-interference ability of the linear motor.
