Active vibration damping of linear oscillatory actuator using DC motor

Research on Control Strategy of Two Dimensional Output Force Vibration Damping Electric Actuator

“…At present, the mainstream vibration reduction method is represented by the electric vibration damping actuator, and the linear force actuator is a typical electric vibration damping actuator [3][4]. It drives a pair of meshing gears by controlling two servo motors, and drives two eccentric wheels to rotate in opposite directions at the same speed to output a single vibration absorbing force with a controllable amplitude and a single direction.…”

“…In the 1990s, the American scholar Kenneth D. Garnjost proposed in the reference [6] the use of a centrifugal electric vibration damping actuator structure, and dual servo motors to drive the eccentric load separately, and proposed a bilateral independent control mode algorithm with controllable output force and amplitude. In reference [7], a linear vibration damping actuator for active vibration reduction is proposed, and the joint simulation of FEM and MATLAB / Simulink is carried out, and the vibration elimination performance of the actuator is verified by experiments [7]. In reference [8], it is pointed out that the phase tracking control algorithm of adjustable mechanical active vibration absorber proposed by Lu Xiqun research group of Harbin Engineering University can realize on-line phase adjustment [7].…”

Reference [9] points out that the control strategy and control algorithm of on-line force actuator in Nanjing University of Aeronautics and Astronautics have been studied, and an experimental prototype has been developed, which has achieved a good vibration elimination effect [9].…”
