Abstract: An elevator system with an elevator car 14, a linear propulsion system to impart force to the elevator car in a hoistway 11, a hoistway communication network 106, 206, a local communication network 110, 210, 310 and motion controls. One of the motion controls proximate to 61 operable to command at least one drive 42A-42F via the local communication network. The at least one drive is coupled to one or more motor segments 22 of the linear propulsion system. The elevator system further includes a controller 46 operable to command the primary control via the hoistway communication network to reposition the elevator car within the hoistway.

Abstract: An elevator car separation assurance system and method of operation includes determining a position and velocity of each one of a plurality of cars by a safety motion state estimator. A safety assurance module of the system is configured to determine a separation map associated with a first car and an adjacent second car of the plurality of cars. The system is further configured to initiate a first separation assurance-induced event associated with at least one of the first and the second cars and based on the separation map. A recovery manager of the system is configured to detect the first separation assurance-induced event, and upon detection, slow at least a third car of the plurality of cars down.

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.

Abstract: An elevator system control system is provided and includes a sensor system configured to sense elevator car conditions, a safety system signaling element to generate a safety signal indicative of an incident and a control system configured to react to the safety system signal. When the control system receives the safety signal indicating that an incident has occurred that requires engagement of at least one of primary and secondary brakes, the control system controls a deceleration rate during the incident by operating the primary brake, determining whether the deceleration rate is within a target range and adjusting the deceleration rate based on signals from the sensor system.

Abstract: An elevator system includes a first elevator car (28) constructed and arranged to move in a first lane (30, 32, 34) and a first propulsion system (40) constructed and arranged to propel the first elevator. An electronic processor of the elevator system is configured to selectively control power delivered to the first propulsion system (40). The electronic processor includes a software-based power estimator configured to receive a first weight signal and a nm trajectory signal for calculating a power estimate and comparing the power estimate to a maximum power allowance. The electronic processor is configured to output an automated command signal if the power estimate exceeds the maximum power allowance.
