摘要：通过引入遗传算法，提出一种用于永磁同步电动机矢量控制伺服驱动系统的新颖设计方法，该方法对电机模型没有依赖性，且可以省去耗时的人工调试工作。不仅外环，即速度环，可以得到自动调节，电流内环的所有PI控制器也均可自动同步寻优。通过链接MAT文件和Matlab环境下的SimPowerSystem工具箱，设计方法得到更好的仿真与验证。

Abstract: This paper presented a novel design method by introducing genetic algorithm to the design of digital permanent magnet synchronous motor (PMSM) servo drive based on vector control, which was modelfree and with little user interaction. Not only the outer loop, ie. speed loop, was automatically tuned, but all the PI controllers including the inner loop (current loop) were also optimized automatically and simultaneously. By linking MATfiles and the SimPowerSystems toolbox under Matlab environment, the whole methodology was better simulated and its verification was tested.
