Course Description

This course trains you in the skills needed to program specific orientation and achieve precise aiming goals for spacecraft moving through three dimensional space. First, we cover stability definitions of nonlinear dynamical systems, covering the difference between local and global stability. We then analyze and apply Lyapunov's Direct Method to prove these stability properties, and develop a nonlinear 3-axis attitude pointing control law using Lyapunov theory. Finally, we look at alternate feedback control laws and closed loop dynamics. After this course, you will be able to...* Differentiate between a range of nonlinear stability concepts* Apply Lyapunov's direct method to argue stability and convergence on a range of dynamical systems* Develop rate and attitude error measures for a 3-axis attitude control using Lyapunov theory* Analyze rigid body control convergence with unmodeled torque

Hanspeter Schaub is the Glenn L. Murphy Chair of Engineering and Professor in Aerospace Engineering Sciences at the University of Colorado Boulder and is the current graduate chair of the aerospace engineering sciences department. He has nearly 20 years of research experience, of which four years are at Sandia National Laboratories. His research interests are in nonlinear dynamics and control, astrodynamics, relative motion dynamics, and relative motion sensing. This has led to approximately 122 journal and 187 conference publications, and a 3rd edition textbook on analytical mechanics of space systems. In the last decade, he has developed the emerging field of charged astrodynamics. Schaub has been the ADCS lead in the CICERO mission and the ADCS algorithm lead on a Mars Mission. He has been awarded the H. Joseph Smead Fellowship, the Provosts Faculty Achievement Award, the Faculty Assembly Award for excellence in teaching, as well as the Outstanding Faculty Advisor Award.
