On-line intelligent control active dynamic vibration absorber and control method thereof

The invention discloses an on-line intelligent control active dynamic vibration absorber and a control method thereof. The on-line intelligent control active dynamic vibration absorber comprises a rotor component, a stator component and a control module, wherein the stator component comprises a first mass block, a second mass block, a first support plate, a second support plate, an excitation inner coil, an excitation outer coil, a magnetic conductive inner barrel and a magnetic conductive outer barrel; the rotor component comprises a base, a first magnetorheological elastomer and a second magnetorheological elastomer; and the stator component is fixed to a controlled system, and the rotor component reciprocates by the elastic restoring force and the material damping force applied by the first magnetorheological elastomer and the second magnetorheological elastomer. According to the on-line intelligent control active dynamic vibration absorber and the control method thereof, the vibration frequency of a main
