ABSTRACT Rail learning is combined with feedback in a control for improving ride quality in an elevator. For example, a pre-stored signal indicative of a horizontal deviation of the rail's surface from a vertical reference is retrieved and used along with a sensed signal indicative of a horizontal position (or other parameter indicative of a disturbance of the elevator) relative to the rail's surface (or a reference) for controlling an actuable horizontal suspension for reducing horizontal disturban- ces of the elevator while guiding an elevator vertically in a hoistway along a rail. As another example, a sensed force signal is averaged over a plurality of trips under differing load conditions and the average is pre-stored for retrieval at various vertical points in the hoistway and may be used, in combination with a feedback loop, to predict horizontal forces about to act on the car.
