摘　　要：针对2.4m跨声速风洞因强耦合、强非线性、大滞后等特性无法获得其精确数学模型,使用经典PID算法控制精度无法满足试验要求的问题,设计基于前馈—模糊PID策略的复合控制器,并应用于风洞试验。试验结果表明,该控制器的应用对于流场控制精度提高有良好的效果。Due to the characteristics of strong coupling,strong nonlinearity and large time delay,the accurate mathematical model of the 2.4 m transonic wind tunnel can not be obtained,and the control accuracy of the classical PID algorithm can not meet the test requirements,so a composite controller based on feedforward and fuzzy PID strategy is designed and applied to the wind tunnel test.The experimental results show that the application of the controller has a good effect on improving the accuracy of flow field control.
