ABSTRACT:
A system and method of adaptively modifying the control signal of a servo system during a mode of acceleration or deceleration. An error accumulator, mean generator, and feedforward generator are used to generate a feedforward signal which modifies the control signal delivered to the servo motor. The feedforward signal for a given mode of operation is determined by the mean error during the previous operation in the mode and by the feedforward signal used during the previous operation in the same mode. Each subsequent operation in the same mode improves the feedforward signal until the mean error is minimized.
