摘　　要：将自整定模糊PID控制方法应用到电液伺服驱动的连铸结晶器振动控制系统中,应用AMES im/S imu link联合仿真技术,建立振动系统模型和控制系统模型,进行系统仿真研究。结果表明这种控制策略不但使系统具有较高的动态响应速度,而且也能保证较高的稳态精度,具有较好的鲁棒性,满足连铸生产的实际要求。A parameter self-adjusting fuzzy-PID technology was adopted to an oscillation control for continuous casting mold.United simulation technique with AMESim and Matlab／Simulink was applied to build the oscillation system model and the control system model.The effect of the proposed control strategy was demonstrated by united simulation of AMESim /Simulink.The simulation results show that the control system has quick dynamic response velocity,good stable precision and robustness.It meets the requirement of continuous casting.
