| 摘 要： | 为了克服传统防喘振控制方法中以缩小压缩机实际工作范围为代价实现稳定运行的弊病，详细分析了压缩机出口紧联控制阀的工作状况并将其作为主动控制的动作机构，将平衡级压缩机的概念引入二阶MG喘振模型。在此基础上，运用反步递推非线性控制方法设计了叶轮压缩机系统喘振的主动控制。结果表明，对叶轮压缩系统施加主动控制，使压缩机在喘振线附近的效率最高点及压升较高区工作，从而增大了工作范围。

| Abstract: | Active control can overcome the disadvantage of traditional anti-surging control methods wherewith stable operation is realized by limiting the actual range of operation.With feedback control the unstable zone on the compressor's performance chart can be stabilized and the compressor made possible to operate near the surge line at a point of highest efficiency within the range of rising pressure.The compressor's working range is herewith enlarged.Based on the widely used second-order MG surge model,an active surge controlled for the turbo-compressor system has been designed by making use of the non-linear back-stepping control principle.Numerical simulation has vindicated its validity.Figs 6,table 1 and refs 9. |
