本文以黎开管内的热声耦合振荡为研究对象,设计基于主动补偿的适应性控制器抑制黎开管内的不稳定燃烧。试验以扬声器为执行机构来改变黎开管的边界条件,从而抑制黎开管内的热声耦合振荡。实时控制效果表明,本文所采用的适应性控制算法能够有效抑制因热声耦合产生的燃烧振荡,为实际动力系统燃烧振荡抑制提供了思路。 In this paper, the thermoacoustic coupling oscillation in the Li Kai tube is taken as the research object, and an adaptive controller based on active compensation is designed to suppress the unstable combustion in the Li Kaipin tube. The experiment uses the speaker as the actuator to change the boundary conditions of the Leikai tube so as to restrain the thermoacoustic coupling oscillation in the Leikai tube. The results of real-time control show that the adaptive control algorithm adopted in this paper can effectively suppress the combustion oscillation caused by thermoacoustic coupling, and provide the idea of ​​combustion oscillation suppression for the actual power system.
