Abstract

Wind tunnels are being used to study the aerodynamic properties of race cars, fighter planes etc. Hypersonic wind tunnels operate at hypersonic speeds ie, with a mach number greater than 6. For doing experiments, it is necessary to maintain a constant pressure in the settling chamber of the tunnel so that we get the desired mach number and mass flow rate through the nozzle. The Back stepping control is a systematic and recursive design methodology for nonlinear feedback control. Here, a back stepping controller is designed using the stabilizing approach and the mass flow rate of hypersonic intermittent blow down type wind tunnel is controlled.

风洞稳定质量流的反演稳定控制器

风洞被用来研究赛车、战斗机等的空气动力学特性。高超声速风洞以高超声速运行，即马赫数大于6。在进行实验时，需要在隧道的沉降室内保持一定的压力，以获得所需的马赫数和通过喷管的质量流量。后步控制是一种非线性反馈控制的系统递归设计方法。本文采用稳定化方法设计了一种反步控制器，对高超声速间歇吹落式风洞的质量流量进行了控制。
