PURPOSE:To provide stable operating characteristics all the time by running a hydraulic elevator actually, detecting a control command value, hydraulic elevator speed, accuracy of arriving at a floor, and elevator car oscillation, and correcting the control command value from these information automatically. CONSTITUTION:A value control controller 131 is provided with a control command generating part 21, a control command value memory part 22, a memory part 23 which obtains an elevator position from a pulse signal from a pulse generator to memorize any displacement between a car floor and a hall floor when an elevator car arrives at the floor, and a memory part 26 which obtains oscillation of the elevator car from the pulse value of the pulse generator and memorizes it. Besides, the previous control current value is corrected and computed by a control command value correcting part 24 based on a previous control current command value which the control command value memory part 22 memorizes and accuracy of arriving at a floor which the floor arriving accuracy memory part 23 memorizes so that floor arriving accuracy and elevator car oscillation may reach prescribed accuracy, and the corrected control current command value is given to a value through a control command value updating part 25 as a new control current command value. |
