To solve the problem that the presetting value of the operating parameters of 2.4m wind tunnel are overly depended on human experience and it's hard to preset the parameters accurately, a rule-based expert system on automated generation of operating control parameters was developed. After a brief introduction on the basic structure of the core control system of the wind tunnel and that of the expert system, the detailed introduction on the design method of the rule-based expert system was depicted. A set of software was developed with C++Builder language, the automated generation of operating control parameters was realized in the wind tunnel. The actual application result shows that the developed expert system has characteristics of high adaptability, wide range and high reliability.%针对2.4 m风洞控制开车参数往往取决于人工经验、难以准确给定控制参数的问题,开发一种基于知识规则的控制开车参数自动生成专家系统.首先简要介绍了2.4 m风洞核心控制系统和专家系统的基本架构,然后详细介绍了开车参数自动生成专家系统的设计方法.采用C++Builder语言开发了一套软件,实现了2.4 m风动主要控制执行机构预置位置参数的自动生成.实际的应用结果表明:该系统具有适应能力强、覆盖范围广、可靠性高等特点.
