摘要
为改善矿用带式输送机永磁同步电机(PMSM)在低速运行时转子信息不易识别的问题,研究了一种基于脉振高频注入法控制方案。该方案将携带转子信息的高频信号通过滤波器提取处理,并通过龙伯格(Luenberger)观测器改善系统的稳定性。经过Matlab/Simulink仿真验证,该方案在矿用带式输送机低速运行时能准确获得转子信息,模型鲁棒性良好。
In order to improve the problem that the rotor information of permanent magnet synchronous motor(PMSM)of mine belt conveyor is difficult to be recognized at low speed,a control scheme based on high frequency pulse injection method is studied.In this scheme,the high frequency signal carrying rotor information is extracted and processed by filter,and the stability of the system is improved by Luenberger Observer.The results of MATLAB/Simulink simulation show that the scheme can get rotor information accurately and the model is robust when the belt conveyor is running at low speed.
