Speed Control of Permanent Magnet Synchronous Motors Using Fuzzy PI Controller Based on Sine Cosine Algorithm

The design of fuzzy PI controller in the speed loop which in the vector control system of permanent magnet synchronous moto(r PMSM)was presented. Aiming at the inability of fuzzy logic controller to adjust parameters adaptively,a new intelligent optimization algorithm-sine cosine algorithm was studied and analyzed,and the important parameters affecting the global exploration and local exploitation ability of the algorithm were adjusted for the more accurate searching results. The improved algorithm was used for the optimization of the fuzzy logic controller's quantization factor and scale factor. The simulation results show that the fuzzy PI control strategy based on sine cosine algorithm has better dynamic performances and anti-interference ability than traditional fuzzy PI control strategy while its robustness is still strong.
