Definitions

  • ABSTRACT A speed pattern generator for elevator control which provides a time dependent-speed reference pattern, with control over maximum jerk directly incorporated into the pattern itself.
  • the speed pattern is developed by starting with a step signal whose two magnitudes determine maximum jerk.
  • the specific magnitude of the step signal which is selected, and time spent at each magnitude of the step signal is determined by acceleration and speed feedback circuits.
  • the step or jerk signal is integrated to provide an acceleration signal, and the acceleration signal is integrated to provide a speed pattern signal which, regardless of how fast the elevator system responds thereto, positively limits the maximum jerk.
