Model and Simulation of New Driving Active Mass Driver System

Abstract:

Aimingto improve the shortcomings of the AMD control system, new direct drivingactive mass driver (DAMD) is developed.The mathematical models of hydraulic power mechanismand hydraulic actuator of DAMD are set up, which leads to the whole equation ofrotation speed-drive force is constructed and the rotational speed of the pump(the driving voltage of servo motor) as input and the active control force asoutput is used. From the above derivation and analysis, the state equation forcontroller structure-DAMD control system is presented. Numerical analysis iscarried out on the structure responding control of the DAMD control system structurewhich is a top designed study object under earthquake load action. Results showthat in some degree,DAMD control system can be used to substitute thetraditional AMD control system for large-span structure to realized activecontrol of structural vibration.
