Controlling sway of elevator cable with movement of elevator car

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.

System and method for group elevator scheduling based on submodular optimization

Systems and Methods for controlling a movement of cars of an elevator system. A processor determines for each car an individual waiting time of each hall call. Determines for each pair of hall calls assigned for each car, a pairwise delay over the individual waiting time of each hall call in the pair caused by a joint assignment of the car to the pair of the hall calls. Approximate a cumulative waiting time of an assignment of the cars to the hall calls as a sum of individual waiting times for each hall call with the assigned car and a sum of all pairwise delays determined between all pairs of hall calls assigned to the same car. Determine the assignment of the cars using a greedy optimization algorithm that greedily assigns hall calls to the cars to minimize the approximated cumulative waiting time, and control the movement of the cars.
