针对中密度纤维板连续热压控制系统非线性、迟滞、时变性及模型参数不确定性问题，在传统PID基础上引入零相差前馈补偿控制策略，完善了PID控制器的性能。在Matlab7．0环境下进行了仿真，结果表明：与常规PID控制器相比较，该控制器明显提高了热压位置伺服控制系统的跟踪精度和响应速度，减少了在高频响应的相位误差，改善了系统的控制性能。

For non-linear characteristic , pure delay and time varying characteristics and model parameters uncertainty of MDF continuous hot pressing control system, we introduced a zero phase feed-forward compensation control algorithm for conven-tional PID controller to improve the performance of the PID controller.Under the Matlab 7.0 simulation environment, the proposed controller can significantly improve the dynamic tracking accuracy and the response speed of the system, reduce the phase error in high-frequency response and improve the control performance of the system.The control performance of the system was improved.
