Anti-windup design for flexible spacecraft attitude control system

This paper considers anti-windup design as one of the approaches to the spacecraft attitude control under input saturation. The anti-windup design provides L₂ gain performance for desired output and guarantees stability in local region subject to input levels. By utilizing the property, we design robust anti-windup compensator for flexible spacecraft attitude control that ensures robust stability against residual mode. The availability is investigated through numerical simulations for spacecraft model of ETS-VIII as a typical example.
