Control Technique of Cage Vibration in Super-High-Speed Elevator (Analysis and Results of Simulation Tests Using Actual Machine)

In order to improve passenger comfort in super-high-speed elevators, we investigated reduction of horizontal vibration transmitted to the cage from bands in the guide rails. First, we added a dead weight AMD (Active Mass Damper) to an elevator cage and roller guide system as a vibration model to investigate the effect on this type of vibration. We used LQ control (Linear Quadratic control), and established optimal control rules. We confirmed this vibration reduction in a model with 4 degrees of freedom by developing a device to simulate actual cage vibration, and carried out experiments that verified our results.
