| 摘 要： | 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。

| Abstract: | Thermoacoustic oscillations in a Rijke tube combustor are considered in this paper. Adaptive control based on active compensation is designed to suppress the unsteady combustion in a Rijke tube.Loudspeaker is used as an actuator.The boundary conditions are changed by the sound wave provided by the loudspeaker,and the thermoacoustic instabilities in Rijke tube will be reduced. Real-time control effects confirm that the adaptive control algorithm adopted in this paper is able to attenuate the combustion oscil... |
