Application of Self-adaptive Differential Evolution Algorithm in PMSM Controller

提出一种自适应差分进化算法,通过进化参数的自适应调整,实现了算法的快速收敛性和鲁棒性.采用本算法设计了永磁同步电机的PID控制器,其中PID参数由本文的自适应差分进化算法进行优化.实验结果表明,经过自适应差分进化算法优化的永磁同步电机转速控制系统的动态特性和静态特性都有明显的改善.

This paper presents a self-adaptive differential evolution algorithm, the fast convergence and robust- ness of this algorithm can be achieved by the self-adaptive adjustment of evolutional parameters. This algorithm is used to design a PID controller for permanent magnet synchronous motor, whose PID parameters are opti- mized by the self-adaptive differential evolution algorithm. The experimental results show that dynamic and static characteristics of the PMSM speed control system, which is optimized by self-adaptive differential evolu- tion algorithm, have been improved significantly.
