ABSTRACT:
Elevator velocity profile generation is based upon combining an open loop, least time profile for acceleration with a precision closed loop, phase plane control for deceleration. The deceleration phase-plane velocity profile is generated as a modified mirror image of the acceleration profile, and transition from open loop control is within ride quality constraints. Adaptive control permits operating a drive unit closer to its limits without danger of overloading under worst case conditions, which account for a small percentage of the time. Thus, smaller drive units can be used in a given application with minimal impact on performance.
