| 摘 要： | 为提高永磁同步电机驱动系统的性能,提出一种无速度传感器内置式永磁同步电机(IPMSM)无差拍直接转矩控制方法。在建立电机离散化模型的基础上,导出了转矩与磁链的无差拍电压控制律。采用图形化辅助解析的方法,直观地表达了无差拍直接转矩控制电压矢量解的物理含义。将无差拍直接转矩控制与基于有效磁链观测器的速度估算方法相结合,实现了IPMSM的无速度传感器控制。仿真结果验证了该方法的有效性。

| Abstract: | To improve the performance of permanent magnet synchronous motor drive system, a speedsensorless deadbeat direct torque control (DBDTC) of interior permanent magnet synchronous motor (IPMSM) was presented. Based on the discrete model of the motor, the deadbeat voltage control law of the torque and flux linkage was derived. By employing a graphical analysis method, the physical meanings of the voltage vector solution were explained clearly. The speed sensorless control of IPMSM was realized by combining the DBDTC and the speed estimation method which based on the active flux observer. Simulation results verified the effectiveness of the proposed method. |
