摘要：
The adaptive spacecraft attitude tracking control with actuator saturation is investigated. The control law consists of both a feedback and a feedforward component. When the feedforward component is restricted to lie within the actuator capabilities, then the closed-loop system is asymptotically convergent in the presence of actuator saturation, which is due to saturation of the feedback component of the control law. A condition on the desired attitude trajectory is obtained, which ensures that the feedforward component of the control law does not saturate that, in turn, ensures asymptotic attitude tracking. The adaptive control is one of the approaches employed to deal with modeling uncertainty, when the unknown system parameters are estimated adaptively.
