摘要
本文较全面地讨论了Ｍ数控制中的压差传感器使用问题，提出了几种利用压差传感器检测Ｍ数控制变量的方法，研究了这些方法对总医误差的传递、判别限的设定以及对控制系统性能产生的影响，介绍了在西工大５２风洞中使用压差传感器调节风洞第二喉道，控制Ｍ数所取得的结果。
The applications o fpressure differnce transducers in Mach number control system are discussed in this paper.Several methods using pressure difference transducers for measuring Mach number comtrolvariabless are introduced.The transfer of the total pressure error,the setting of error restriction and the error influences to the performance to the performance of the control system are investigated.The results using pressure difference transducers for controlling Mach number in NPU high speed wind tunnel are given.
