摘要
针对电机旋转坐标系下直轴与交轴电流耦合的问题,采用对角矩阵解耦控制方法,通过在电机的电流环中增加一个解耦器矩阵,将励磁电流id与转矩电流iq解耦成互不干扰的量,保证电机输出转矩的精准性。仿真试验结果表明:与前馈解耦控制方法、反馈解耦控制方法相比,该方法在电机转速较高或电机参数发生变化时,鲁棒性更好,解耦效果显著。
For the coupling problems of d-axis and q-axis currents in the synchronous rotating frame, the diagonal matrix decoupling control method is proposed. The field current i4 and torque current i4 are decoupled into no-interfering variables by increasing a decoupling compensator in the motor current loop, so as to ensure the accuracy of PMSM＇s output torque. Furthermore, this method is compared with the feedforward decoupling control method and the feedback decoupling method. It is shown that the proposed method has better robustness and decoupling effect when the motor speed is high or the motor parameters change.
