基于可控度/鲁棒性的框架结构综合设计研究

A Study on the Mix Design of Frame Structures Based on Controllability/Robustness

在对框架结构进行振动主动控制时,为获得尽量大的系统可控度和良好的鲁棒性,把结构设计与控制器设计相结合进行综合设计,在保证框架结构基本性能的前提下重新修改原结构以达到较好的控制效果.此外在优化过程中,考虑到综合设计计算较复杂且计算量也较大,文中引入了改进的遗传算法,通过改进将其应用于综合设计.最后给出了计算实例,该算例表明这一方法是有效的.

In order to acquire the biggest controllability and the best robustness for active vibration control of frame structures, a mix design which combine structural design with controller design is considered. Original structures are redesigned to get a better control involved. Considering the complexity of the calculation in the mix design and the amount of work during the optimization of the structures, a mended genetic algorithm is used to search for optimal designs results. Finally, a numerical example is provided to show the effectiveness of the method.
