ABSTRACT:
A control apparatus for hydraulic elevators, including: a flow control valve for controlling the amount of oil in a hydraulic jack; a sensor device for detecting at least one of oil temperature and load pressure and producing corresponding input data; a correcting rule storing device for storing correcting rules of control instruction values corresponding to input data from the sensor device; a fuzzy reasoning processor for calculating control instruction values as fuzzy values from the input data and the correcting rules; a speed pattern correcting circuit for correcting the control instruction values based on the fuzzy values calculated by the fuzzy reasoning processor; and a speed controlling device for supplying the corrected control instruction values to the valve.
