Velocity control method for elevator |
摘要 |
A method for controlling the velocity of an elevator cage by determining the optimum time delay between a velocity command signal for an elevator cage and actual movement of the cage responsive to the velocity command signal. The actual time delay is increased or decreased based on a comparison of the actual time needed for the cage to reach its maximum deceleration and the theoretical time needed for the cage to reach its maximum deceleration. The new time delay is introduced into the velocity command signal to thereby control cage velocity.
