| 摘 要： | 在永磁同步电机数学模型的基础上，分析了最优转矩控制（MTPA）原理，得到了在dqO坐标系下转矩与d、q轴电流的关系式。为便于实际应用，利用MatIab工具给出了最优转矩控制的近似实现方法。建立基于该方法和凸极式永磁同步电动机模型的仿真控制系统进行仿真验证，仿真结果表明该方法是有效可行的。

| Abstract: | The principle of maximum torque per ampere （MTPA） control based on the mathematical model of permanent magnet synchronous motor was analyzed and the relationship between torque and current in dqO coordinate system was given. To facili- tate application in practice, an approximation implementation method of optimal torque control was obtained by means of Matlab software. Then the simulation model of control system was established, which was based on the method and salient-pole permanent magnet synchronous motor model, The simulation results show that the method is feasible and effective. |
