vpApplication of PSO-GWO optimization algorithm for PI optimization in permanent magnet synchronous motor

A PI (proportional integral) control parameter optimization method based on particle swarm optimization improved grey wolf algorithm is proposed to address the issues of insufficient parameter adjustment accuracy, slow response speed, and poor stability in traditional PI control for permanent magnet synchronous motors (PMSM). To improve the issue of the traditional grey wolf optimization algorithm easily falling into local optima and causing a decrease in accuracy, the position update strategy of the particle swarm algorithm is applied to the position update of the grey wolf algorithm, effectively enhancing the global optimization capacity of the grey wolf algorithm. By establishing a simulation model of the PMSM vector control system and conducting hardware-in-the-loop experimental tests, the motor system response of the improved grey wolf algorithm and traditional PI control is compared and analyzed. The results show that compared to optimizing PI control parameters using traditional methods, the improved grey wolf algorithm significantly enhances the response speed, anti-interference capability, and robustness of the PMSM control system.
