Abstract
Aiming at the disadvantages of traditional AMD drive device，such as large volume，high cost， complex system，more energy consumption，an innovative driver-Direct Driving Volume Control ( DDVC) servo system for AMD is proposed based on the volume control of electro-hydraulic servo system. The mechanical models of motor control，hydraulic power mechanism，hydraulic actuator and other sub-structures of DDVC electro- hydraulic servo system were separately established as well as the mathematical model of direct drive volume control electro-hydraulic servo actuator. Taking an actual project's experimental prototype as a standard， the parameter optimization and the match computation were carried out，and the DAMD control system are designed and processed. The dynamic characteristics of the power mechanism controlled by pump are not high because the DAMD system dynamic characteristics are low. DAMD control system can be used to substitute the traditional AMD control system for high-rise structure or large-span structure to realize active control of structural vibration.
