摘要： An elevator control apparatus comprises a torque command generating device for generating a torque command, a converter device for supplying electric power to a motor for driving an elevator car, a car position calculation device for calculating the present position of the elevator car, a compensation device for calculating an unbalanced rope torque on the sides of the elevator car and a counterweight from the torque command generated by the torque command generating device and the present position of the elevator car calculated by the car position calculation device, a load weighing device for detecting a load in the elevator car, and a final torque command supply device for adding outputs of the compensation device and the load weighing device to the torque command generated by the torque command generating device and supplying the torque command as a final torque command to the converter device. According to the apparatus, since the unbalanced load is compensated and the elevator car is driven according to the compensation, the riding quality of the elevator car is improved.
