摘 要
 线性系统控制理论的发展已臻完善,而对非线性时变系统的研究正方兴未艾。模糊控制器具备自学习、自适应、自组织能力，能够自动辩识被控制过程参数、自动整定控制参数、能够适应被控制过程参数的变化；其次，它又具有常规PID控制器结构简单、鲁棒性强、可靠性高、为现场工程人员所熟悉等特点。正是这两大优势，使得智能PID控制成为众多过程控制的一种较理想的控制装置。
 气动技术在国外发展很快，在国内也被广泛的应用于机械、电子、轻工、纺织、食品、医药、包装、冶金、石化、航空和交通运输等各个部门。气动机械手、组合机床、加工中心、自动生产线、自动检测和实验装置等已大量涌现，他们在提高生产率、自动化程度、产品质量、工作可靠性和实现特殊工艺等方面显示出极大的优越性。
 本文研究使用模糊控制器（Fuzzy）对非线性的气动传动系统进行设计和仿真，主要针对气动系统在纺织、食品方向上的应用。使用气动方向阀、节流阀将系统向所要控制位置锁定，并使之快速响应，并使用其他元件和一些辅助装置实现气体的净化、过滤、干燥等。最后，在MATLAB SMULINK环境下对系统运行情况进行了仿真，确定了其实现快速响应和保持位置的方法。
 该设计是模糊控制控制气动传动系统在清洁生产方面的一个典型方案。

ABSTRACT
 Linear systems control the development of the theory Yizhen perfect, and the nonlinear time-varying systems of the study is the ascendant. Fuzzy controller with self-learning, adaptive, self-organizing capacity, can be controlled automatic identification process parameters, automatic setting control parameters, to be able to control the process parameters of change; Secondly, it is conventional PID controller simple structure, Robustness of the strong, high reliability and engineering staff to the scene, and other familiar features. It is precisely these two advantages, making smart PID control as many of the process control an ideal control device.     Aerodynamic technology in foreign countries has developed rapidly in China have been widely used in machinery, electronics, light industry, textile, food, medicine, packaging, metallurgical, petrochemical, aviation and transportation departments. Pneumatic Manipulator, the combination of machine tools, machining centers, automated production lines, automatic detection and experimental equipment, etc., have emerged in large, they increase productivity, the degree of automation, product quality, reliability and work to achieve special technology and other areas show great advantages .     In this paper, the use of fuzzy controller (Fuzzy) of non-linear pneumatic transmission system design and simulation, mainly pneumatic system in the textile, food on the direction of the application. The direction of the use of pneumatic valve, throttle valve system to control position to be locked, and the rapid response and the use of other auxiliary components and devices to achieve some of the gas purification, filtration, drying, and so on. Finally, in MATLAB SMULINK environment of the system is running in the simulation to determine their rapid response and keeping methods.     The design is fuzzy control aerodynamic control transmission system in the clean production of a typical programme.
 KEY WORDS: fuzzy controller, pneumatic transmission, the time delay
