| 摘 要： | 2m×2m超声速风洞是一座大型引射下吹式风洞，总压控制具有非线性、时变、大滞后特性，引射器和主调压阀同时运行时存在一定的耦合特性。为了满足风洞试验对总压控制精度和收敛速度的要求，对不同马赫数试验条件下，风洞流场启动和串级智能稳定控制策略进行了深入研究，并在调试过程中对控制方法进行了验证，控制结果达到风洞指标要求。

| Abstract: | The 2m× 2m supersonic wind tunnel is a large injector blowdown wind tunnel, which has nonlinear, time-varying and large delay time characteristics. The interference and cou- pling between the total pressure control system and injection control system always occur in the injection test mode. In order to satisfy the requirement of the control system that must be of quick response and high stable-state accuracy, the control strategy is studied deeply and the method has been applied to this system successfully. |
