Abstract: An optimum design method based on particle swarm optimization (PSO) algorithm was pre?sented for PID controller of an artillery servo system. A new performance criterion evolution function combined with the system maximum position settling time, rise time, overshoot, steady state error, constant velocity position tracking error and sinusoidal position tracking error was defined. It is fast to calculate a PID controller to minimize the evaluation function by searching on the given controller pa?rameter space. The simulation results show that the proposed controller is effective.
