摘要

旋转失速和喘振是轴流压气机中的两种主要的不稳定工作形式，限制了压气机稳定工作范围。本文中提出了一种新的对旋转失速和喘振的非线性反馈控制策略，即把压升作为反馈信号，来补偿节流阀系数值。研究结果表明，这种控制策略很简单，但是能够消除失速时伴随的迟回效应；也能够增加压气机的喘振裕度。

Abstract

Rotating stall and surge are two major unstable forms in axial flow compressors and limit the maximum range of the stable performance of the compressors. A new control strategy with nonlinear feedbacks for the rotating stall and the surge is proposed in this paper. The pressure rise is considered as a feedback to compensate the value of the throttle coefficient. The results show that the new control method is simple but can destroy the hysteresis loop associated with rotating stall so that it is avoided that the compressor enter into the surge.
