Research on Sliding Mode Control of Horizontal Vibration of High-Speed Elevator Car System
In order to improve the robustness of the elevator lift car control system and ensure its ride comfort,this paper designs an adaptive sliding mode control(IM-SMC)strategy to attenuate the horizontal vibration of the system.Compared with passive vibration reduction,regardless of light or heavy load conditions,the maximum reduction in horizontal vibration displacement and acceleration of the IM-SMC controlled car system is basically over 80％,indicating that the elevator operates stably and comfortably;Moreover,there is no significant fluctuation in the coupling and aerodynamic excitation forces on the lift car,and the active suppression effect is good.And through application verification,the average elevator travel time under IM-SMC control is reduced to 38.1 seconds,improving elevator performance.
