摘要
为解决目前无传感器控制在永磁同步电主轴上的局限性,设计了一种脉振高频电压注入法和模型参考自适应法(MRAS)相结合的复合观测器。在低速段采用脉振高频电压注入法,中高速段采用模型参考自适应法,并在过渡区间内设计出新的切换方法以此来满足低速段向中高速段的平滑过渡,从而实现永磁同步电主轴全速度范围无传感器控制。系统在10 N阶跃负载的冲击下,转子位置误差仅为0.004 rad/s,调整时间仅为0.2 s。仿真实验结果表明,所设计的复合观测器在全速度范围内追踪精度高,动态响应速度快,鲁棒性强,从而提高了永磁同步电主轴的动态性能及稳定性。
In order to solve the limitation of the current sensorless control on the permanent magnet synchronous motorized spindle,this paper designs a composite observer combining the pulsed high-frequency voltage injection method and the model reference adaptive method(MRAS).The pulse vibration high-frequency voltage injection method is adopted in the low-speed section,the model reference adaptive method is adopted in the medium-high-speed section,and a new switching method is designed in the transition interval to meet the smooth transition from the low-speed section to the medium-high-speed section,so as to achieve permanent Sensorless control of the full speed range of the magnetic synchronous motorized spindle.Under the impact of 10 N step load,the rotor position error is only 0.004 rad/s,and the adjustment time is only 0.2 s.The simulation results show that the designed composite observer has high tracking accuracy and dynamic response in the full speed range.The speed is fast and the robustness is strong,thereby improving the dynamic performance and stability of the permanent magnet synchronous motorized spindle.
