Title: Nonlinear driving profile generation e.g. for stepper motor - integrating acceleration and speed at each position, loading acceleration values formed by profile generator when acceleration changes required during motion
Inventor: ERSCH WALTER DIPL ING
IPC: G05B19/416
Filed: 1991-04-11
Abstract: The non-linear drive profile generation involves integration of acceleration and speed values at each position. For acceleration variations, corresp. changed acceleration values are loaded during motion. All data required to form a new acceleration value are acquired by the process running in the profile generator which picks up the instantaneous integration states. The process generates new acceleration values from the integration states and stored acceleration values taking account of the desired speed and position at exactly defined, reproducible points on the drive profile. USE/ADVANTAGE - E.g. for use with stepper motor, method enables non-linear drive profile to be generated whilst eliminating errors associated with changing acceleration values.
