Abstract: According to an aspect, an elevator system includes a propulsion system having a plurality of motor segments forming a primary portion and a plurality of drives to impart force on a secondary portion coupled to an elevator car. The elevator system also includes a controller operable to identify a local neighborhood of the drives and determine a health status of each of the drives within the local neighborhood. The controller is further operable to adjust a thrust command per active drive of the local neighborhood based on at least one of the health status and a position of each active drive of the local neighborhood with respect to the secondary portion.
