摘要
通过由两个压电作动器控制的空间桁架,将最优控制问题和结构中杆件截面积动态优化相结合,综合分析了二者的混合优化问题.计算结果表明,在结构动态响应特性不变的条件下,结构重量和控制需求均有显著下降.
Under the constraints to meet the requirements of dynamic features of structures, a hybrid optimizing algorithm is formed by minimizing the control energy and the structural weight. A 72 bars space truss with two piezoelectric actuators is used to illustrated the complete process of the algotithm. It is shown that the control energy and the structural weight are reduced obviously by using the proposed methods.
