摘　　要：针对锻造操作机大车行走液压伺服系统高性能控制的需求,基于传统PID控制的行走系统难以取得高性能控制的问题,对锻造操作机的大车行走系统进行了系统的模糊控制实验研究。采用了一种解析式模糊控制器,该模糊的控制规则库具有确定的数学模型,解析表达式类似于传统PID结构,参数整定可以借助于PID的整定方法来获得,避免了传统模糊设计存在的较大随意性和经验性。锻造操作机大车行走系统的控制实验研究表明,与传统的PID控制器相比,该方法具有超调小、控制精度高、鲁棒性强以及便于工程实现等优点,是锻造操作机大车行走系统以及相似液压伺服系统控制的一种切实可行的方法。For requirements of the high performance control on forging manipulator cart walking hydraulic servo system and the difficulty in achieving high performance control of the walking system under traditional PID control, the experimental research of fuzzy control the forging manipulator cart walking system was carried out systematically. A new type of fuzzy controller was adopted ~ and the fuzzy control rule database had a determinate mathematical model. Because the fuzzy controller structure was similar to the conventional PID, the parameters of the fuzzy controller could be adjusted by the conventional PID to avoid the randomness existed in traditional fuzzy design and experiences. The experimental study shows that, compare with the conventional PID controller, the fuzzy controller method has advantages of small overshoot, high control precision, strong robustness and easy engineering implementation, etc. , and it provides a feasible method for the forging manipulator cart walking system as well as the similar hydraulic servo system control.
