以电液比例系统的应用实例为基点，将模糊集合图、从属函数、模糊语言与推理、模糊控制器的结构原理等模糊控制的基本概念引入电液比例系统。详细介绍了一个单输入单输出的模糊控制电液比例压力系统的系统参数确定方法及试验结果，说明了结合微机进行电液比例系统的模糊控制是切实可行的。
Based on the application example of electro-hydraulic proportional system, the basic concepts of fuzzy set, membership function, fuzzy language and reasoning, and the structural principle of fuzzy controller are introduced into electro-hydraulic proportional system. This paper introduces in detail the system parameters determination method and test result of a single-input / single-output fuzzy control electro-hydraulic proportional pressure system, which shows that it is practicable to combine fuzzy control of electro-hydraulic proportional system with microcomputer.
