Abstract
A control method based on the theory of nonstationary sliding mode control is presented for an application to suppression of transeverse vibration of elevator rope. The transverse vibrations of ropes of high-speed elevator are caused by a resonance with sway of building which is subjected to an earthquake and big wind, hence, an effective solution is demanded. The nonstationary sliding mode control is effective for the control of elevator rope categorized by a time-varying system and robust for nonlinearity of a control device. In this paper, therefore, the vibration control for the elevator rope is performed based on the nonstationary sliding mode control using an input system which has gaps between an actuator and the rope because of preventing abrasions of rope. The suppression performance of the proposed method is examined by the numerical calculation on the condition of practical use. Consequently, the numerical results indicate that the performance of the proposed method is remarkable.
