摘要
在基于模型参考自适应观测器的PMSM无速度传感器控制中,以有限集模型预测控制替换传统的PI控制器,省去复杂的PI调节器整定环节,引入估计转速以扩展有限集,解决固定有限集存在的估计转速有限问题。通过分段滤波估计转速以减少计算量。在MATLAB/Simulink环境下以及TI DSP TMS320F28377S实验平台上,将该控制方法结合矢量控制并与传统模型参考自适应控制进行仿真、实验对比验证。结果表明:该控制方法对表贴式PMSM具有较好的动态及稳态性能。
In the speed sensorless control of PMSM based on model reference adaptive observer, the traditional PI controller is replaced by finite set model predictive control, which saves the complex PI regulator tuning. The estimated speed is introduced to expand the finite set to solve the problem of limited estimated speed in fixed finite set. The estimated speed is given by piecewise filtering to reduce the amount of calculation. In MATLAB/Simulink environment and on TI DSP TMS320F28377S experimental platform, the control method is combined with vector control, and simulation and comparitive experiment are carried out on traditional MRAS control, with the results indicating that the control method has better dynamic and steady-state performance for surface mounted PMSM.
