PI Controller Parameter Setting of PMSM Speed Control System based on Pigeon-inspired Optimization Algorithm

In order to solve the problem that PI controller has difficulty in parameter setting in PMSM, a PI parameter setting method for PMSM speed control system based on modified pigeon-inspired optimization algorithm is proposed. The algorithm of pigeon-inspired optimization was combined with Powell search algorithm, so that the convergence speed was improved by using the direct search characteristic of Powell algorithm. The PI controller parameters are taken as the output of the algorithm, and the optimal PI control parameters can be obtained after several iterations. Simulation results show that the PI controller optimized by the modified pigeon-inspired optimization algorithm has good robustness. The proposed method greatly reduces overshoot and shortens response time.
