智能结构及其控制系统集成优化设计

THE INTEGRATED OPTIMIZATION OF INTELLIGENT STRUCTURES AND CONTROL SYSTEMS

将智能结构的振动控制性能指标和集成结构的质量作为目标函数，结构尺寸参数和控制系统的控制参数同时作为独立的设计变量， 并施加约束条件， 从而将智能结构及其控制系统集成优化设计问题转化为多目标数学规化问题。数值结果表明， 利用本文方法设计出的智能结构及其控制系统， 能极大地抑制系统的振动。

Conventional structural sizing variables and elements of the feedback gain matrix are both treated as the independet design variables,the performance index of vibration control and the mass of the integrated structure are chosen as objective functions,and some constraints are included in the optimization.Then,the integrated optimization of intelligent structures and control systems is converted into multiobjective optimization.The numerical results show that the in telligent structure and the control system designed by the present method can greatly suppress the vibration of the structure.
