摘要
为解决永磁同步电机(PMSM)无位置传感器控制策略在中高速阶段对模型参数依赖度大,起动阶段或低转速运行阶段对转子状态信息估算精度低的问题,采用旋转高频电压信号注入法与模型参考自适应法相结合的复合控制策略,以两者加权的方法实现全转速范围PMSM高精度控制。通过Matlab/Simulink仿真及试验平台验证,该方法能够实现从低速到中高速的平顺切换,提高了控制系统的动态稳定性,具有动态调节能力强、鲁棒性好等优点。
In order to solve problem that the sensorless control strategy of permanent magnet synchronous motor(PMSM)has a large dependence on model parameters in the middle and high speed phases,the estimation accuracy of rotor state information is low in the start-up phase or the low-speed operation phase,a compound control strategy combining the rotating high-frequency voltage signal injection method and the model reference adaptive method is adopted,and the high-precision control of PMSM in the whole speed range is realized by the weighting method of the two methods.Through Matlab/Simulink simulation and test platform verification,this method can achieve smooth switching from low speed to middle and high speed,which improves the dynamic stability of the control system,and has the advantages of strong dynamic adjustment ability and good robustness.
