Abstract: To deal with the difficulties in optimal controller design for coupled and nonlinear permanent magnet synchronous motor(PMSM) servo system, a novel proportional integral derivative(PID) controller design method was proposed based on particle swarm optimization(PSO) algorithm. Considering overall evaluation of the system performance, a new evaluation strategy was introduced during the optimization process. The experimental results show that the optimized PID controller has rapid response and low overshoot, and can effectively improve the dynamic performance for the servo system.
