Multiphase traction elevator controller and method of use

A multiphasic traction elevator control system for an elevator car in an elevator shaft, comprising:

• a central controller, configured to generate a set of speed commands for the elevator car based on a set of profiles;
• a motor room board, operatively connected to the central controller, and configured to relay the set of speed commands to a traction drive motor, operatively connected to the elevator car;
• a car panel controller, operatively connected to the central controller, configured to receive a set of user inputs and transmit a set of destination requests to the central controller, related to the set of user inputs;
• a hall panel controller, operatively connected to the central controller, configured to receive a set of call signals and transmit the set of call signals to the central controller;
• a position sensor, operatively connected to the central controller, configured to monitor a velocity and a position of the elevator car within the elevator shaft;
• a communication interface operatively connected to the central controller, the motor room board, and the hall panel controller;
• and
• a motion planning module, stored in a memory unit of the central controller, and when executed by the central controller, causes the system to:
• calculate a first S-curve motion profile, comprising an acceleration phase, a cruising phase, and a deceleration phase;
• adjust a maximum possible speed, Vmax, based on a travel distance;
• accommodate a mid-flight destination change by recalculating a velocity profile;
• and
• execute a stop rejection mechanism that prevents an intermediate stop if a requested floor is too close to a current position of the elevator car, or requires exceeding a predefined acceleration threshold for the elevator car.
