摘要
导出了一种基于功率流的结构半主动瞬时控制算法 ,其基本原理是保证在控制力作用的每一个时间段控制力吸收的功率大于零 .并以在相邻主 -从结构间设置半主动控制装置来减小主结构振动为例 ,分析了该控制算法的有效性 .
A semi active control algorithm based on power flow absorption is proposed which guarantees the control force to absorb power at every time step. The proposed strategy is used to reduce the response of the primary structure using the interaction between the primary and auxiliary ones. This control strategy is compared with that based on the classical linear optimal control algorithm. The numerical examples are used to demonstrate the effectiveness of the control law.
