Abstract

Apparatus for controlling an elevator car driven by an induction motor, characterized in that it includes: A device for generating a speed control signal; A device for generating a real speed signal; A device for comparing the speed control signal and the actual speed signal in order to generate a resulting difference signal; A delay characteristic circuit having a first switching device for applying a delay characteristic to the resulting difference signal when the first switching device is in a first state and for applying any delay characteristic to the resulting difference signal when the first switching device is in a second state; A saturation signal generator circuit having its input connected to the delay characteristic circuit output and having a second switching device for generating a saturation signal that is applied to a distribution circuit when the second switching device is in a first state and for applying the output of the delay characteristic circuit to the distribution circuit when the second switching device is in a second state; By switching the first switching device from its first state, its second state is sufficient at a given deceleration decision point and switching is made from its second state to its first state, when a deceleration control point is reached; switching of the second switching device from its second state to its first state after the end of the acceleration and switching from its first state to its second state at the beginning of the deceleration.
