| 摘 要： | 分散控制与集中控制策略相比可以提高结构控制系统的可靠性。文中将分散控制和滑移模态控制算法原理相结合,导出分散滑移模态控制(decentralized sliding mode control,DSMC)算法并应用于高层结构振动控制中。该方法是将结构分解为若干个子结构,分别进行滑移模态控制。文中以某20层钢结构Benchmark模型为例,分别进行3个子结构与4个子结构的分散控制数值计算,与线性二次型最优控制(Linear quadratic optimal control,LQR)效果相比,DSMC算法可以有效地抑制结构位移和加速度反应。

| Abstract: | Decentralized control strategy is superior to centralized control strategy in improving the reliability of the control system.By introducing the decentralized control strategy and combining it with the Sliding Mode Control(SMC),an algorithm named Decentralized Sliding Mode Control(DSMC) is derived for the vibration control of tall buildings.In the approach,the building is divided into several substructures and a separate SMC algorithm is designed for each subsystem.A 20-storey benchmark building is divided into three or four substructures as an example for comparing the performance of the control algorithm.The numerical results of DSMC,which could effectively reduce structural displacement and acceleration responses,are better than those of LQR. |
