PURPOSE:To adjust it to an ideal velocity curve in a short time without using any measuring instrument by adding a compensation value, eliminating a step difference between a sped reference conformed to a distance up to the stopped floor and a landing speed reference, to the speed reference, and shifting a decelerating command point. CONSTITUTION:A speed reference operational part 9, where both output signals of a landing detection switch 6 and a pulse generator 8 are inputted, monitors where is a cage 1 situated in an elevator shaft 2 at all times, and it operates a speed reference conformed to a distance up to a position where it should be stopped next, on the basis of cage position information, by a command out of an auto tuning command generator 10. The speed reference operational part 9 generates two types of speed reference, namely, a speed reference V1 being decelerated at a tilt beta from a decelerating command point S1 and a land ing speed reference V2 ranging from a speed reference starting point S2 to a stop position, and a difference V1-V2 at time of this translation is operated and stored in memory. In addition, a compensation value DELTAs to a decelerating command point S for eliminating this difference is calculated, adding this com pensation value DELTAS to the decelerating command point S. |
