Classification: G05B

Abstract:
A machine control apparatus, comprising:processing circuitry;a user interface communicating with the processing circuitry and configured to receive user input commands defining at least in part a desired velocity versus time profile of a point of interest on a machine;a data storage device configured to store user input commands and a target displacement value for the moving point of interest, the target displacement value associated with an actual physical displacement of the point of interest on the machine;an integrator communicating with the processing circuitry and configured to integrate the desired velocity versus time profile and derive a displacement value for the moving point of interest;a comparator communicating with the processing circuitry and configured to compare the target displacement value with the derived displacement value for the point of interest; andthe comparator configured to output a scaling factor calculated by the processing circuitry and operative to scale the velocity profile to realize the target displacement value as integrated over a time domain of interest.
