Abstract: This paper proposes the use of electrodynamic booms for satellite attitude control. By manipulating the magnitude and direction of electrical currents flowing through each boom, the induced Lorentz force acting on the booms can be harnessed as thrust and torque. This can potentially combine the spacecraft propulsion and attitude control systems into one package. This work presents the mathematical formulation of the electrodynamic torque and examines a feedback control algorithm to regulate the spacecraft angular velocity and orientation with respect to an inertial frame. The control algorithm is tested in simulation for several mission scenarios.
