提出了一种利用活塞驱动对压缩机进行主动喘振控制的新方法。对两种控制律进行比较，以评估实施该概念的可行性。第一个控制律是通过使用反步推导得出的非线性反馈控制，第二个控制律是通过分析工作点附近的线性化系统的特征值得出的线性反馈控制。非线性反馈控制律使闭环系统全局渐近稳定（GAS）并采用全状态反馈。线性反馈控制仅使用来自增压室压力和活塞速度的反馈，并且质量流量反馈的去除对于实施是有利的。具有线性反馈控制的闭环系统在工作点附近局部渐近稳定。仿真表明两种控制器都能够稳定浪涌。© 2011 ASME
A novel approach to active surge control in compressors using piston actuation is presented. Two control laws are compared in order to evaluate the feasibility of implementing the concept. The first control law is a nonlinear feedback control derived by using backstepping and the second one is a linear feedback control derived by analyzing the eigenvalues of the linearized system around the operating point. The nonlinear feedback control law makes the closed loop system globally asymptotically stable (GAS) and uses full states feedback. The linear feedback control is only using feedback from plenum pressure and piston velocity and the removal of the mass flow feedback is advantageous for implementation. The closed loop system with the linear feedback control is locally asymptotically stable around the operating point. Simulations show that both controllers are capable of stabilizing surge.© 2011 ASME
