Abstract
The use of the geomagnetic Lorentz force as a means of actuation is considered in this paper for the purpose of spacecraft formation reconfiguration. A continuous/impulsive linear quadratic regulator (LQR) is proposed for the purpose of designing an optimal control strategy that combines continuous Lorentz force actuation with impulsive thrusting. New theory is presented for the determination of optimal impulsive thrust application time. A simulation of a spacecraft formation reconfiguration maneuver demonstrates the effectiveness of the continuous/impulsive LQR.
