Speed Control System of PMSM Based on Artificial Bee Colony PID

针对永磁交流伺服系统高性能的调速要求,提出采用人工蜂群算法优化的PID控制器,应用到永磁同步电机矢量控制系统的速度环中。将待优化参数看作蜜源,利用蜂群特有的角色转变机制搜索优质的参数组合,设计了包含超调惩罚项的适应度函数。仿真结果表明,与传统PID控制器相比,人工蜂群PID控制器能使系统速度响应更快,且几乎无超调,实现了速度的精确跟踪,显著提高了伺服系统的动态性能和稳态精度。

In view of the high performance of the permanent magnetic AC servo system, the artificial bee colony algorithm was proposed for tuning the parameters of the PID controller, and it was applied to the speed loop of the vector control system. By using the transition mechanism, the PID parameters were viewed as honey to search the best parameters, and the fitness function contains overshoot penalty was designed. The simulation experiments show that comparing with the traditional PID controller, the ABC-PID controller has faster response and lower overshoot. It realizes precise track of speed and it can highly enhance the dynamic performance and stability of the servo system.
