摘　　要：本文首先针对电流位移相位差这一控制算法，导出了电磁阻尼器（ＡｃｔｉｖｅＭａｇｎｅｔｉｃＤａｍｐｅｒ－ＡＭＤ）动力特性的理论计算公式，其次详细探讨了静态电流、电流位移相位差以及控制器增益等参数对ＡＭＤ动力特性的影响规律；最后提出了一种实测ＡＭＤ刚度阻尼系数的方法．Based on the phase control algorithm,a theoretical formula is derived for calculating the dynamic properties of an active magnetic damger (AMD) expressed with stiffness and damping coefficients. Furthermore,the relations among AMD dynamic characteristics, the static current, the controller gain and thephase are discussed by digital simulation and experiment. Finally,an experimental approach is presented forthe measurement of AMD stiffness and damping coefficients.
