ABSTRACT:
A system for generating substantially constant area pulses suitable for application to an inertial instrument torquer. The torquer current pulses are directly utilized to provide an averaging feedback loop wherein the variations in pulse width due to errors in switching pulse times are offset by amplitude control for the pulses. With this system, variations in width of the torquer current pulses are offset in a high speed, closed loop manner with compensation occurring within the pulse interval.
