项目摘要

9713415AnnaswamyWe propose to study active control combustion dynamics, with particular emphasis on suppression of thermoacoustic instability. Our approach is to develop a systems framework which will include (a) models for the different components which contribute to the instability, e.g., the heat release dynamics, the acoustic dynamics, the actuator-sensor dynamics, (b) the effect of active feedback control on these components and their mutual interactions, and (c) self-tuning algorithms as part of the control design to allow changes in the operating conditions of the process. Each subcomponent model will be studied in increasing order of complexities which are compatible with practical systems, e.g., heat release dynamic models for bluff body-stabilized combustion, in vortical structures in shear layers, from fuel injectors used as actuators, etc. We will focus on showing, using a systems framework, how an overall controlled combustor model which is synthesized using these component models is capable of describing the subtle dynamic behavior observed in practical systems. Particular attention will be given to an understanding of model-based control strategies that are based on the predicted response of the combustion systems using these models and that account for effects not previously understood, such as coupling among acoustic modes and coupling among different controller components and the combustor. ***

9713415ANNASWAMYWE建议研究主动控制燃烧动力学，特别强调抑制热声不稳定性。我们的方法是开发一个系统框架，该框架将包括（a）导致不稳定性的不同组件的模型，例如，热释放动力学，声学动力学，执行器传感器动力学，（b）主动反馈控制对这些组件及其相互作用的影响及其相互作用的影响，以及（c）自我调节的操作条件，可以进行操作。每个子分量模型将以越来越多的复杂性顺序进行研究，这些模型与实际系统兼容，例如，剪切层中的易热燃烧模型，在剪切层中的涡流结构中，来自用作执行器的燃料注射器等涡流结构等。我们将使用这些动态模型，使用这些模型，使用这些模型，这些模型是使用这些模型，这些模型是在这些模型中，这些模型的范围是同步的，实用系统。特别关注对基于模型的控制策略的理解，这些策略基于使用这些模型的燃烧系统的预测响应，并说明了以前无法理解的效果，例如声学模式之间的耦合以及不同控制器组件和燃烧器之间的耦合。 ***
