An elevator is indispensable vertical transport, especially for high-rise buildings. With regard to elevator control, it is important to quickly suppress the vertical vibration occurring in the car in order to improve the performance and quality. The authors proposed the Damping Support Control (DSC) that uses a method for reducing residual vibration which has been researched for the low rigidity machineries, and presented an optimal parameter design method for the control system. However, it was recently found that a vibration phase and frequency synchronized between the car and the counterweight, a motor-torque difference of a driving sheave would have been minute. Thus the DSC applying the motor control of traction machine was unable to work enough to extinguish the residual vibration. This paper presents that it is possible to effectively reduce the residual vibration by installing a damping support mechanism in the counterweight, and using this in combination with the DSC as a measure to solve this problem.
