ABSTRACT:
A control system for a positioning device includes a controller connected in a feedback loop. The controller calculates a current for supply to the positioning device according to the error between a desired current value and a measured current value. This current is converted to a voltage by an amplifier and further modified by a feedforward voltage calculated using mechanical and electrical characteristics of the positioning device and a desired position and/or desired derivatives of position.
