A Time-Periodic Control Law for Satellite Magnetic Stabilization

Adrian-Mihail Stoica and Vasile Dragan
Abstract—The paper presents a design methodology for the automatic control system of a satellite with magnetic actuators taking into account the time periodic variation of the Earth’s magnetic field. The design method is based on using an optimal 2 H controller with periodic coefficients. These coefficients depend on the solution of a specific system of coupled Riccati type equations. An iterative numerical algorithm to solve such system is also presented. The proposed design procedure is illustrated by a case study for a CubSat in which the benefits of using a a time-periodic controller are emphasized.

Index Terms—H optimal control, satellite stabilization, system of coupled Riccati equations, time periodic control law.
