摘要
介绍西北工业大学NF-3低速翼型风洞稳速压控制系统的结构、控制原理和性能特点,由于采用了先进的模糊控制技术,传感器实时校准和变系数程控技术,解决了速压系统不建模自动调节,速压过程参数变化自适应和测量、控制、数据处理一体化等技术关键,使风洞速压控制达到高效和高品质性能。
This paper describes the structure,principle of control and characteristics of the stable dynamic pressure system for the low speed airfoil wind tunnel in Northwestern Polytechnical University.The dynamic pressure control of the wind tunnel has got high efficiency and high quality due to the use of fuzzy control,real time calibration of pressure transducer and varying coefficient programme control,which resolves the nonmodel automatic control of dynamic pressure system,adaptive change of dynamic pressure process parameter and measurement,control and data processing in an integral.
