μ設計を用いた超高速エレベーター用アクティブ制振技術の開発

抄録

Recently, many super high rise buildings are built in the rising nation. Elevator lateral vibration is one of the main problems affecting ride comfort in elevators. In the ultra-high-speed elevator, peculiar vibration is activated and it is difficult to maintain ride comfort by the conventional vibration suppression technique. We have developed an active cabin vibration control system to suppress the lateral vibration of ultra-high-speed elevators. In this research, the application of μ - synthesis to this system is dealt with, so that the performance to suppress vibration and the robustness about several parameter errors are investigated. In addition, we simplified the controller design and made implementation of the controller easy by simplifying μ - synthesis process. We manufactured the active cabin vibration control system and the experimental device to verify vibration reduction effect in ultra-high-speed elevators. Experimental results show that the active cabin vibration control system is capable of reducing the lateral vibration of ultra-high-speed elevators.
