PURPOSE:To carry out elevator landing control of high accuracy and control that provides comfortableness in riding on an elevator, without being affected by fluctuations in power source voltage, etc., by determining a gain during deceleration of a control system according to the deviation of a speed command signal produced before the start of deceleration of the elevator, from a speed detection signal. CONSTITUTION:When the output signal of a compensating means 112 becomes negative, a braking gain setting means 115 is operated to calculate a gain correction value according to the deviation of a speed command signal produced before the start of deceleration of an elevator from a speed detection signal. Next, the correction value is added to the existing braking gain to compensate for the lack of the gain. Thus, highly accurate elevator-landing control is enabled together with control that provides comfortableness in riding on the elevator, without being affected by fluctuations in power source voltage, etc. |
