IMPROVED ELEVATOR RELEVELING CONTROL

A system for releveling an elevator car floor with a landing floor includes a load weight sensor to sense a load weight of an elevator car at a landing floor, and a releveling controller operably connected to the load weight sensor to calculate a corrective velocity for the elevator car based on the...

description	A system for releveling an elevator car floor with a landing floor includes a load weight sensor to sense a load weight of an elevator car at a landing floor, and a releveling controller operably connected to the load weight sensor to calculate a corrective velocity for the elevator car based on the load weight and estimates of the effective stiffnesses at the landing floor. A machine is operably connected to the releveling controller with both feedback and feedforward control and the elevator car to apply the corrective velocity to the elevator car thereby reducing a mismatch between the elevator car and the landing floor.
