Control-Structure Interaction in Structural Vibration Control

Research on the control of the structure has been done a lot already, but control-structure interaction was seldom considered. Some scholars have done research on actuator-structure interaction and developed hydraulic and linear motor model respectively and presented that there exits generally a dynamic coupling between the actuator and the structure. This paper mainly investigates the actuator-structure interaction in the active control of structures. First, Analyse the structrual dynamical characters and responses under the wind load and confirm an AMD control programme appropriate to the structure. Then Analyse and compare the control effect of coupling and uncoupling. The investigation includes three aspects aimed at the two actuators: hydraulic actuators and linear motor. First, influence of coupling and uncoupling for the structure is discussed; second, we adjust parameters of the two actuators to investigate the influence on the coupling; finally, we adjust control parameters to investigate the influence on the coupling.
