| 摘 要： | FL 7风洞是以三台航空发动机为动力的跨音速风洞 ,通过调节发动机转速、柔壁及旁路活门开度来实现对M数的控制。影响M数的因素较多 ,很难建立精确的数学模型 ,为了提高M数控制速度和精度 ,在新改造的FL 7风洞测控系统中 ,采用了模糊控制、自学习等控制策略 ,取得了良好的效果。笔者对控制方法和控制规则作了介绍。

| Abstract: | FL 7 is a continuous transonic wind tunnel,which is powered by three engines.Mach number is adjusted by the rotating speed of engines,the flexible wall nozzle and the by pass valve.It is difficult to establish the precise mathematical model,because there are many aspects influencing the Mach number.We use the fuzzy control with function of self learning for getting better in speed and precision of Mach number control.And then we have got more satisfied results.This paper describes the methods and the rules of control. |
