We proposed a new vibration control mechanism and control method for cabin horizontal vibration of super-high-speed elevators. An AC servo motor and ball screw on the car frame drive the control force to the cabin where the horizontal vibration is to be suppressed. The vibration of the cabin, detected by an acceleration sensor, is integrated to determine the velocity and the position. The control force is determined based on the above position and velocity, and on the velocity of a motor encoder taking into account the car dynamics. The derived dynamics of the elevator car with a control mechanism and the effect of vibration control was verified by numerical simulations. The results indicate good performance of the vibration control system, which can suppress the 1st- and the 2nd-mode vibrations of the car. Control force and actuator stroke remained within the practical extent of designed values.
