Random optimal vibration-control for a double-part combination of isolated structures
双单体组合隔震结构振动随机最优控制

Two building structures neighboring each other are linked with actuators,and one of them is isolated,then a new pattern of structure,a combination of isolated structures,is formed.The vibration and control equations of this new system are derived in this paper.Regarding the input of earthquake as a white noise and using the principle of random optimal control,features of vibration control and effect of parameters such as isolation degree,damping and ground site are analyzed.The conclusions indicate that vibration-control system of combined structures can bring the seismic responses of structures under effective control by optimizing the control parameters of structure,and the cost of control can be reduced.
