A control apparatus for an elevator system in which a rotation speed of a drive motor for driving said elevator system in controlled by supplying a deviation signal obtained by comparing a speed signal of said drive motor including an induction motor with a driving pattern setting signal; said control apparatus comprising a time function generating circuit operated by means of retarding instruction signal supplied from the elevator and for generating a speed instruction output signal which decreases lineally to zero when a elevator cage approaches to a stop position in a distance of the elevator travelling, a correcting instruction circuit for supplying a correcting signal depending on an error signal of a drive motor or a speed instruction signal of said time function generating circuit, with respect to a reference speed signal, to said time function generating circuit.
