摘　　要：针对传统液压驱动主动质量驱动系统(AMD)装置复杂、体积大、能源利用效率低等缺点,提出了采用直驱容控电液伺服作动器(DAMD)驱动的AMD控制系统.分别建立了直驱容控电液驱动系统的电动机控制、液压动力机构和液压执行机构等子系统的数学模型,进一步建立直驱容控电液伺服作动器的数学模型;以某实际工程的试验样机为标准,进行参数优化及匹配计算,设计并加工了DAMD控制系统;对DAMD控制系统进行了性能试验.试验结果表明,直驱式系统本身动态特性较低,其根本原因是泵控动力机构的动态特性不高.DAMD控制系统在一定范围内可以代替传统的液压驱动AMD控制系统,实现对高耸、大跨等长周期结构振动的主动控制.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.
