    Abstract: An elevator system includes an elevator car supported by an elevator rope wrapped around a sheave, such that a rotation of the sheave changes a length of the elevator rope between the sheave and the elevator car thereby controlling a movement of the elevator car within an elevator shaft of the elevator system. An elevator cable is connected to the elevator car and the elevator shaft to carry electrical signals to the elevator car. The operation of the elevator system is controlled in response to receiving a call for a movement of the elevator car requesting a change of the length of the elevator rope. A motion profile of the elevator car causing the requested change of the length of the elevator rope that minimizes the sway of the cable is determined according to a model of a cable relating a sway of the cable to a motion profile. Next, the motion of the elevator car is controlled according to the determined motion profile.

    Abstract: A method of operating an elevator system is provided. The method includes powering, using a battery, the elevator system when an external power source is unavailable. The method also includes controlling, using a controller, a plurality of components of the elevator system. The controlling comprises operating at least one of the battery, an elevator car, a drive unit, and a brake. The method further includes determining, using the controller, a run profile of the elevator car in response to a selected deceleration. The method yet further includes operating, using the controller, the elevator car in response to the run profile determined, and determining, using the controller, an actual velocity of the elevator car.
