【Abstract】 A speed control system of brushless DC motor is inseparable from PID controller with excellent performance.Aiming at the on-line optimization of PID parameters,the flower pollination algorithm was introduced,and the integral square error was taken as the objective function. The optimization method was applied to PID regulation to realize brushless DC motor speed control. The experimental results show that compared with the traditional PID control system,the speed control system of flower pollination algorithm has better robustness,faster response time and higher control accuracy.更多还原
