Abstract :
Based on state space model of the DC-Servo system, a high dynamic synergetic control method is proposed in this paper. The relationship of weight coefficient parameters variation, reaching law and system response is analyzed. This control strategy makes the system have quick and stable starting process as well as good dynamic characteristics. The synergetic control method is verified feasible and effective by simulation results. After quantitative calculation, the steady-state error of the system is 0.00025° and overshoot of the system is 0.0167%.
