A micro-vibration testing platform with symmetrically placed electromagnetic actuators for the control of micro-vibration is presented. At first, a mathematical model of the micro-vibration platform is established for the simulation of micro-vibration control with an adaptive method. Then, an experiment is conducted to verify the control effectiveness. Both the simulation and the experiment demonstrate that the micro-vibration of the platform can be suppressed.
