针对随机激励下的以结构参数为变量、以控制输入力最小化为优化目标的建筑结构和控制系统并行设计问题,设计了一种基于线性矩阵不等式工具的并行优化算法.该算法在以下两个方面突破了现有算法的局限性:将质量矩阵纳入优化变量,拓宽了优化范围;采用凸化势能函数处理将控制引入结构设计导致的非凸约束,大大降低了算法复杂度.算例分析结果显示该算法能有效提高结构设计效能.

Aiming at the parallel design problem of building structure and control system under random excitation with structural parameters as variables and minimizing control input force as the optimization goal, a parallel optimization algorithm based on linear matrix inequality tool is designed. The algorithm breaks through the limitations of existing algorithms in the following two aspects: the quality matrix is included in the optimization variable, which broadens the optimization scope; The convex potential energy function processing is used to introduce control into the non-convex constraint caused by structural design, which greatly reduces the complexity of the algorithm. The analysis results show that the algorithm can effectively improve the efficiency of structural design.
