摘要
提出了一种基于d-q坐标系下的永磁同步电机的解耦电流控制方法,采用该方法相对于静止坐标系下的电流环,可大大减小电机定子电流的稳态误差。对该方法进行了数学推导与仿真研究,仿真结果表明,该方法有效地实现了I_d、I_q完全解耦,电流环具有良好的跟踪性能。
A decoupling control method of current loop based on d-q coordinate is presented in this paper. The steady-state error of current can be reduced greatly compared with that based on still coordinat-e. Mathematical derivation is carried out and simulation study as well. The simulation results show that the current loop with this method have good decoupling effect and satisfactory tracking performance.
