摘要
矿用伺服电机在煤矿井下作业过程中,带载启动等复杂工况经常干扰其位置跟踪的准确性。为解决这一问题,搭建矿用伺服电机Simulink仿真系统,提出一种基于速度与电流前馈-反馈复合控制结构,有效提高了匀速与加减速阶段位置跟踪准确性。不同负载启动情况下矿用伺服电机位置响应仿真结果表明,重载启动时在速度与电流前馈补偿下系统位置跟踪的平均误差降低了48.6%,保证了在2倍额定负载情况下伺服电机位置跟踪的稳定性。
During the operation of mining servo motor,complex conditions such as loaded start-up often interfere with the accuracy of position tracking.To solve this problem,constructed a Simulink simulation system for mining servo motor and proposed an anti-interference control structure based on velocity and current feedforward control,which effectively enhances the accuracy of position tracking during constant speed and acceleration-deceleration phases.Simulation results of position responses of mining servo motor under different load start-up conditions show that under speed and current feedforward compensation,the average tracking error of the system decreases by 48.6%during heavy load start-up,which ensures the stability of servo motor position tracking even under the twice rated load condition.
