Classification: CPC B | IPC B

Claim 10:
11. A control system for an elevator system in a hoistway of a building, the control system comprising:
at least one detector to determine a plurality of characteristics of building sway, wherein the at least one detector provides an indication of an amplitude of movement, a frequency of the movement, and a direction of the movement; and
a controller configured to
receive an indication of building sway,
determine the plurality of characteristics of the building sway comprising frequencies and corresponding periods of building sway,
determine a relationship between the characteristics of detected sway of the building and a configuration of elevator system components in the hoistway,
determine an expected sway of at least one elongated member of the elevator system based on the characteristics, and
control at least one of position and movement of the elevator in the hoistway based on the expected sway of the at least one elongated member and the determined relationship including using a first control strategy when the determined characteristics comprise a first set of characteristics or a second control strategy when the determined characteristics comprise a second set of characteristics, wherein the first set of characteristics is different than the second set of characteristics and the first control strategy is different than the second control strategy, and wherein the direction comprises at least a side-to-side direction relative to the hoistway or a fore-aft direction relative to the hoistway, and wherein the first control strategy is used for the side-to-side direction and the second control strategy is used for the fore-aft direction.
