Attitude Control of Solar Sail Spacecraft with Saturation
Solar sail spacecraft attitude control is the basis of its application and has important practical significance and extremely high theoretical value. Based on a class of solar sail spacecraft with rigid-flexible coupling, a novel quadratic α-stable controller is designed to stabilize the system. In consideration of the saturation constraint problem of controller outputs, this paper designs a compensator, which is used for the loss compensation of the controller caused by the saturation constraint, and weakening the performance degradation of the closed-loop system caused by saturation. Numerical simulation shows that the designed controller and anti-saturation compensator can realize the asymptotic tracking of the attitude angle of the solar sail, and suppress the vibration of flexible mode, and solve the problem of output saturation effectively.
