Title: Method and device for elevator dc drive motor stabilization
Inventor: KAEHKIPURO MATTI
IPC: B66C13/30
Filed: 1986-05-05
Granted: 1991-04-02
Abstract: ABSTRACT OF THE DISCLOSURE         A method and a system for elevator DC drive motor speed control stabilization employ current data and speed data as feed-back information.  The elevator speed control systems currently in use are incapable of con-trolling the elvator speed without delay, which causes problems with high-speed elevators in particular.  The present invention is designed to avoid these problems by approximating the current regulator by means of an ideal integrator.  The mathematical model thereby obtained is used for determining amplification and time constants of control system speed loop or loops, and these system parameters are compensated by providing short instruction accentuations in order to achieve practically delay-free compliance with instructions.
