Control of Nonlinear Spacecraft Attitude Motion
Spacecraft Dynamics and Control,
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

What people are saying
active students enrolled simultaneously
In some questions, the right answer is outright wrong given the information in the question.The course relies a lot on the discussion forum in these cases, however the teaching assistance is non-existant and the low number of active students enrolled simultaneously makes its usefulness limited for debugging.For the sake of its contents, I really recommend this course, however the quizzes require some major rework for an entirely satisfactory learning experience.
entirely satisfactory learning experience
nonlinear spacecraft attitude motion
Concept such as Lyapunov Stability Theory, Lyapunov functions, general elemental velocity Lyapunov function, Lyapunov attitude control properties, control theory, integral feedback, feedback gain, feedback control laws are analyzed, and compose over all the course "Control of Nonlinear Spacecraft Attitude Motion.
assessed needs major reconsideration
Interesting course but the way the course is supported and course work is being assessed needs major reconsideration.
makes its usefulness limited
also introduces some practical
This course also introduces some practical aspects such as: non linear integrator for dealing with dynamics uncertainty, gain tuning and how to dealing with actuator saturation.
better understand kind
By passing this course, I better understand kind of stabilities.
general elemental velocity
material will result
I really learned a lot from this course.However the numerical quizzes requiring simulation are often badly explained, and many times, small details that are not mentioned in the course material will result in a wrong answer.
non linear integrator
often badly explained
provides basis technic
This course provides basis technic for defining nonlinear control law base on Lyapunov function.
