Classification: CPC B | IPC B

Claim 19:
20. A control system for an elevator system in a hoistway of a building, the control system comprising a controller configured to:
receive an indication of building sway;
determine a plurality of characteristics of the building sway including frequencies and corresponding periods of the sway of the building;
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, wherein the components of the elevator system comprise at least elongated members of the elevator system, and wherein determining the relationship between the characteristics of the sway of the building and the configuration of the elongated members of the elevator system includes
using information regarding building design and building sway modes,
using information regarding the configuration or features of the elongated members,
establishing relationships between sets of characteristics of the sway of the building and resulting sway of the elongated members, and

determining the expected sway of the elongated members based on the relationships.
