Elevator control device for plural traction units |
摘要 |
An elevator control device for controllably driving multiple traction units includes position sensors and current supplies. Each of the current supplies includes a position controller for generating a speed command for the corresponding traction unit based on input difference between a common position command for the traction units and a feedback signal derived from an output of the pertinent position sensor, a speed controller for generating a current command for the corresponding traction unit based on an input difference between the speed command generated by the position controller and a feedback signal obtained by differentiating the output of the pertinent position sensor, and a current controller for supplying an electric current to the corresponding traction unit based on the current command generated by the speed controller.
