Rope sway mitigation via rope tension adjustment

An elevator system comprising:

• an elevator car having a plurality of ropes operably connected thereto;
• a sway detection sensor configured to detect sway of at least one component of the elevator system and/or a building in which the elevator system is disposed;
• and
• a rope tension adjuster in operable communication with the sway detection sensor, the rope tension adjuster configured to increase a tension of at least one of the individual ropes of the plurality of ropes and to decrease a tension of at least one of the individual ropes of the plurality of ropes to mitigate excitation of natural frequencies of at least one of the plurality of ropes when the sway detection sensor detects sway of the at least one component of the elevator system and/or the building.
