Fuzzy control of spacecraft attitude maneuver with actuator saturation

Spacecraft attitude control is investigated via fuzzy control systems subject to actuator saturation and delta operator approach. The spacecraft attitude control model is transformed into a fuzzy delta operator system with appropriate fuzzy rules. The stability of fuzzy delta operator systems with actuator saturation is studied via Lyapunov approach. Then a sufficient condition on stability for fuzzy delta operator systems is given and a fuzzy controller is designed. Lastly, an example of spacecraft attitude control is considered to show the effectiveness of the proposed results.
