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.
