Nonlinear spacecraft attitude control
6/8 November 2023
Overview and General Information:
Spacecraft attitude control laws are often designed using linear control design techniques. As a result, their effectiveness can be guaranteed only for small attitude angles and small angular velocities since in that situation a linear approximation of the attitude equations can be employed. However, there are occasions when the spacecraft motion involves large attitude angles and large angular velocities. For those motions, the full nonlinear attitude equations must be used for evaluating the effectiveness of attitude control laws. In this course, basic results of Lyapunov stability theory will be presented and applied to nonlinear spacecraft attitude control.
