| 摘 要： | 本文介绍了风洞高度模拟控制系统的构成和控制原理,根据控制特点选取了增量PID控制算法控制补气调节阀开度,针对直接采用增量PID控制算法对风洞总压控制效果不太理想的问题,分析了影响控制效果的原因,提出了采用超前调节的解决措施,并进行了系统调试。调试结果表明：总压控制精度和稳定过渡时间都有明显改善,为风洞总压控制的改进提供了方法。也为类似大惯性、大滞后特性系统的精确、稳定控制提供了参考。

| Abstract: | This paper introduces the construction and control principle of altitude simulation control system in Wind Tunnel. System chooses the increment PID control arithmetic to control adjusting valve. Because of the problem that the effect of adopting the increment PID control arithmetic is bad, analysises the reason, suggests the method that adopting advance adjust, then carries out system debugging. The result indicates that: the pressure control precision and transion time are improved obviously, that provieds the method for pressure control in Wind Tunnel, and provides reference for the stabilization control of the system that is much inertial. |
