中文摘要：

将主体的概念应用到结构声有源控制中，探讨智能降噪技术。分析一个包含两弹性板的矩形封闭空腔内的耦合声场特性。由于简支的两弹性板之间的耦合很弱，耦合效应被忽略，因此考虑在两个弹性板上分别作用一点力致动器，并综合智能控制算法，构造内部结构基本相同的两个控制器主体。应用协调体结构中的竞争和从属协调机制将两个控制器主体耦合起来，并采用分散顺序控制，由此建立一个完整的基于多主体的结构声有源控制系统。尽管单个主体采用的单通道自适应反馈控制算法仅适用于窄带噪声控制，但多主体联合控制则可实现更宽频带噪声的衰减。同时，利用冗余的主体，控制系统还可以防止一个或多个主体的失效，因此控制系统具有强鲁棒性。另外，系统还具有分散式控制的可扩展性、并行运算以及易于执行的特点。

英文摘要：

The concept of the agent is applied to the active structural acoustic control for intelligent noise reduction technology. The coupled sound field characteristics inside an enclosure with two elastic plates are investigated. Due to the coupling between the two elastic plates is very weak, the coupling effect is neglected. In view of this situation, the point force actuator is applied on each of the two elastic plates. And the controller agents are constructed by integrating the intelligent control algorithm and the actuators. The two controller agents are coupled into an integral multi-agent-based active structural acoustic control system by the coordination object which includes the competitive and subordinate coordination mechanisms. The distributed sequence control is adopted for the control system. Although the single channel adaptive feedback control algorithm used by individual agent is only suitable for narrow-band noise control, multi-agent joint control can suppress the broader frequency band noise. At the same time, the control system can tolerate failures in one or several of the agents by redundant agents. Hence, it has the strong robustness. In addition, the system has the scalability, parallel computing and simpler implementation of the distributed control.
