无速度传感器的PMSM最优转矩控制系统研究

Study on the PMSM optimal torque control for a non-speed-sensor system

针对无速度传感器控制系统模型,采用PMSM的数学模型和最优转矩矢量控制方案,建立了基于模型参考自适应的观测器,解决了转子速度位置的估计问题。理论分析和仿真结果表明,所提出的永磁同步电机无速度传感器矢量控制系统的转速辨识方法具有较强的鲁棒性和较好的动静态性能。

For a non-speed-sensor system model, the PMSM model and the optimal torque control is applied. We build a model reference self-adaptive controller to estimate the speed and position. Both the theory and simulation results show that the controller is flexible and with the satisfactory performances.
