Abstract: A magnetic torquer (10) for spacecraft attitude control, providing a torque that is controllable over an extended range greater than a normally used linear range, and thereby providing a higher ratio of maximum torque to device weight. In one form of the torquer, a feedback loop including a sensor (20), a signal subtraction circuit (24), a controller (28) and an adjustable power supply (16), continuously determines a corrected command signal that results in the generation of a desired magnetic moment and a corresponding torque, over the extended range, regardless of non-linearity across the extended range. In an alternate form of the torquer, the corrected command signal is generated from a mathematical model (56) of the magnetic torquer (10). Use of the invention also minimizes the effect of any residual magnetic moment that might by present when the actuating current is reduced to zero.
