复杂结构重叠分散控制理论研究与数值分析
Theoretical investigation and numerical analysis of overlapping decentralized control for complex structure
摘要
Abstract
This paper presents two overlapping decentralized control methods for complex civil engineering structures.One is applying the system inclusion principle to obtain the decoupled gain matrix of controllers and filters.The other is proposed to achieve decoupled control force between the overlapping portions of the subsystems,which is based on the classical linear quadratic Gaussian (LQG) control algorithm.And the design procedure for overlapping decentralized control is put forward.Moreover,various kinds of overlapping decentralized control strategies for complex structures,including ordinary chain-shaped,ring-shaped,star-shaped and ring-star-sharped schemes,etc,are considered and compared in this study.A 9-story Benchmark building is selected as a numerical example to implement multi-overlapping decentralized control design methods.Results show that both design methods and the multioverlapping decentralized control schemes (chain-shaped,ring-shaped,star-shaped,etc) achieve good performance,and the star-shaped overlapping decentralized control scheme performs the best among various overlapping decentralized schemes.关键词
