项目摘要
Smart structures consisting of smart sensors, smart actuators and smart cluster control has been proposed, the validity of the proposal being verified. Moreover, a systematic design procedure of the smart structure systems has been established.Different from conventional mechanical systems, smart structure systems alter their specifications assigned by a designer autonomously, chasing the optimal control effectiveness in accordance with environmental variability. Main outcomes obtained in this year are summarized as follows.1 Derivation of acoustic modal functions of a strongly coupled structural/acoustic cavityDue to the strong coupling between structural fields and acoustic fields, eigenvalues and eigenfunctions of both the structural fields and acoustic fields differ from those in vacuo ones. Hence when suppressing acoustic potential energy in the cavity, it is impossible to carry out the control design of a target system unless perfect eigenvalues and eigenfunctions of the coupled system are known. To cope with the problems in the above, the research project succeeded in deriving the acoustic eigenfunctions of the strongly coupled structural acoustic cavity.2 Development of distributedsmart sensorsIn order to extract the acoustic power modes of the smart structures, distributed smart sensors have been presented, the systematic design procedure of the smart sensors being established.3 Active control of smart structuresEmploying smart sensors, smart actuators and smart control theory proposed in the project, control effectiveness theoretically achievable is clarified.
提出了由智能传感器、智能执行器和智能集群控制组成的智能结构,并验证了该方案的有效性。并建立了智能结构系统的系统设计流程。与传统的机械系统不同,智能结构系统可以根据环境的可变性,自主改变设计者分配的参数,追求最优的控制效果。今年取得的主要成果总结如下强耦合结构腔声模态函数的推导由于结构场和声场之间的强耦合,结构场和声场的本征值和本征函数都不同于真空腔。因此,在抑制腔内声势能时,除非知道耦合系统的完美本征值和本征函数,否则不可能对目标系统进行控制设计。针对上述问题,本课题成功推导了强耦合结构声腔的声学特征函数分布式智能传感器的发展为了提取智能结构的声功率模式,提出了分布式智能传感器,建立了智能传感器的系统设计流程智能结构的主动控制利用本课题提出的智能传感器、智能执行器和智能控制理论,阐明了理论上可实现的控制效果。
