针对液压控制系统中广泛存在的同步控制问题，提出一种新的基于模糊PID增量式输出的主从方式控制策略，并通过在MATLAB下编写仿真程序对某型号机床的液压同步控制系统进行建模和仿真。结果表明：该控制策略的控制效果很好，对液压同步控制系统的设计和调试具有一定的指导意义。 A new masterslave mode control strategy based on fuzzy-PID and incremental output was put forward for hydraulic synchronous control problems which widely existed in hydraulic control system. By modeling and simulation in MATLAB for the hydraulic control system of some type machine tool, the control strategy is proved effective, and it also provides guidance for the design of hydraulic synchronous control system.
