An active inertial damper system (100) and method for damping vibrations (V1,V2) in a structure (11). An inertial mass (2) is supported by a support frame (1) via spring means (3) to form a mass-spring system (2,3) having a resonance frequency (fn). A controller (6) is configured to control a force actuator (4) to adapt the driving force (Fd) as a function of measured vibrations (V1,V2). The controller (6) comprises a filter (H) determining a magnitude (M) of the driving force (Fd) as a function of frequency (f) for the measured vibrations (V1,V2) in the structure (11). The filter (H) is configured to provide an anti-resonance dip in the magnitude (M) of the driving force (Fd) at the resonance frequency (fn) of the mass-spring system (2,3) to suppress resonant behaviour of the mass-springsystem (2,3) itself. 种用于结构(11)中减振(V1,V2)的主动惯性阻尼器系统(100)及方法。惯性质量(2)经由弹簧装置(3)由支撑构架(1)所支撑，用以形成具有共振频率(fn)的质量-弹簧系统(2，3)。控制器(6)构造成以控制力致动器(4)顺应该驱动力(Fd)随着该经测量的振动(V1,V2)而变化。控制器(6)包括滤波器(H)确定该驱动力(Fd)的大小(M)随着用在该结构(11)中该经测量的振动(V1,V2)的频率(f
