Mixed-sinusoid-based path optimization method for spacecraft attitude maneuvers

Spacecraft agile-maneuver technology is one of the primary assurances and prerequisite for high-solution space remote sensing task. Matching with the abilities of the actors and the sensors, a mixed-sinusoid-based maneuvering path is proposed. Not only the advantage of sinusoid maneuver path over appendices vibration excitation is kept, but the time optimality of the step curve is taken into consideration, through which the maneuver speediness and the excited vibration smoothness are conciliated. The designed path in some sense optimizes the maneuver time, which is especially suitable for large-angle and agile-maneuver path programming of spacecraft with relatively rigid appendices. Numerical simulation illustrates that mixed-sinusoid-based maneuver path reaches time approximate optimality and performance approximate optimality simultaneously.
