This paper presents a synthesis method of nonstationary sliding mode controller with time-varying switching hyperplane for reducing the vibrations of rope of elevator. The proposed method deals with a variation of system in time domain continuously because the controller with time-varying hyperplane is designed based on the time-varying Riccati equation. The controlled system is modeled on a structure including an elevator system and it is implemented by the time-varying controller and VSS observer. Then the performance of this controller is verified through the numerical calculation in the two cases that the elevator descends and ascends when the structure is subjected to Chi-Chi earthquake.
