将同步控制思想应用在振动打桩机中，实现在线无级调频调矩，从而提高打桩效率。针对电液伺服系统存在的非线性、时变性以及模型不确定性等特点，利用单片机的计算优势，融合复合式同步控制策略和模糊控制理论，构成一种智能型模糊PID参数同步控制系统。实验结果表明：模糊P1D控制器可以改善系统的动态特性，控制效果明显优于常规PID控制器。

To improve the efficiency of pile driving and achieve stepless frequency and torque online regulation, a scheme of synchronized control was used in the control of vibratory pile drivers. In view of nonlinear and time varying characteristics of the electro--hydraulic servo system, an intelligent synchronized control system with fuzzy PID parameters was developed, taking calculational advantages of single--chip microcomputer（SCM） and compromising composite synchronization control scheme and fuzzy control theories. Experimental results indicate that the fuzzy PID controller can improve the dynamic characteristics and its control effect is better than that of conventional PID controller.
