<P>PROBLEM TO BE SOLVED: To provide a speed control device for an elevator which can be constituted inexpensively and can reach a floor with high accuracy and comfortable ride quantity. <P>SOLUTION: The speed control device for the elevator comprises a pulse generator 6, a position detector 7, a remaining distance calculator 10, a speed command generator 11, and a speed controller 14. The speed command generator 11 has a remaining distance pattern data table 13 formed by previously calculating relations among the remaining distance, speed command, and a time taken until arrival at the floor at a time of elevator arrival at the floor in a case having no time delay of a control system. The speed control device has a control means for controlling a hoist that extracts the arrival time corresponding to the present remaining distance from the remaining distance pattern data table, adds the time delay to the extracted arrival time, extracts a speed command corresponding to the arrival time considering the time delay from the remaining distance pattern data table again, and thus can arbitrarily change the time delay of the control system. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
