Attitude control system of a super-high speed elevator car based on magnetic guides

摘要

This paper describes a new attitude control system of a super-high speed elevator car based on magnetic guides. Using a conventional roller guide system for attitude control of a super-high speed elevator car (810 m/min class) will result in serious horizontal vibration caused by the winding guide rails which are installed in the hoist way to guide the elevator car. The new control system proposed realizes acceleration control to suppress the car vibration at high speed running. The system is based on a magnetic guide controlling the attractive power between the guide rails and electro-magnets which are fixed to the elevator car frame. The effectiveness of the proposed method is confirmed by computer simulation and experimental results obtained using full scale equivalent testing equipment.
