Abstract: The stability of rigid spacecraft attitude is considered. The mathematical model of spacecraft system is described by quaternion. The robust nonlinear attitude controller without angular velocity measurement is designed based on passivity-based approach. The designed attitude controller has no information related to system parameters. So it has robustness to model error and uncertainty of model parameters. The stability of spacecraft attitude control with considering external disturbance can be proved by applying Lyapunov approach and LaSalle Invariance Principle. Numerical simulation results demonstrate the effectiveness of the designed attitude controller.
Keywords: Attitude control, Passivity, Quaternion, External disturbance.
