摘　　要：包装机械的捆扎设备常采用永磁同步电机转矩控制方式,永磁同步电机自配有光电和霍尔传感器检测转子位置,本文研究永磁同步电机在仅有霍尔传感器时转矩控制方法,包括利用平均加速度法进行转子位置估算,在电机速度突变或者是加减速阶段时,相邻两个Hall区间不再是保持不变的,因此引入平均加速度法估算转子位置,进一步降低估算的误差,提高电机的控制性能;设计电流环线性自抗扰控制器提高系统抗扰动性,包括三个主要的模块:跟踪微分器、扩展状态观测器、状态误差反馈控制,具有更好的鲁棒性和抗干扰能力。经实验测试和现场运行验证了采用仅有霍尔传感器的永磁同步电机应用于捆扎设备的可行性,从而有效减少电机体积,控制生产成本。Mechanical strapping equipment often adopts the torque control mode of permanent magnet synchronous motor,which is equipped with photoelectric and Hall sensors to detect the rotor position.This paper studied the torque control method of permanent magnet synchronous motor when there was only Hall sensor,including estimating the rotor position by using the average acceleration method,designing the current loop active disturbance rejection controller to improve the anti-disturbance performance of the system,simulating the PMSM torque mode by using Matlab/Simulink,and finally carrying out the on-site installation test of the baling conveyor belt.The feasibility of applying permanent magnet synchronous motor with Hall sensor to bundling equipment was verified by experimental test and field operation,thus effectively reducing the motor volume and controlling the production cost.
