摘要 |
A control system for an AC elevator system in which an actual speed of an elevator car is compared with a speed command and control is made so that deviation between the actual speed and the commanded speed becomes zero.

A motoring torque or a braking torque is additionally generated in dependence on a load on the car in a region close to the target landing position. |
