METHOD AND DEVICE FOR STABILIZING SPEED CONTROL OF ELEVATOR DC DRIVE MOTOR

摘要

A method and device for elevator DC drive motor speed control stabilization system in which current data and speed data are used as feed-back information. The current regulator is approximated by an ideal integrator, and mathematical model thereby obtained is used for determining the amplification and time constants of the control system speed loop or loops, and these system parameters are compensated by providing short instruction accentuations for achieving practically delay-free compliance with instructions.
