Control of Nonlinear Spacecraft Attitude Motion

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

FAQ

When will I have access to the lectures and assignments?

Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:

What will I get if I subscribe to this Specialization?

When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile. If you only want to read and view the course content, you can audit the course for free.

Is financial aid available?

Yes. In select learning programs, you can apply for financial aid or a scholarship if you can’t afford the enrollment fee. If fin aid or scholarship is available for your learning program selection, you’ll find a link to apply on the description page.

Reviews

Excellent course but it could have been smoother if the instructor kept himself in loop with people doing the course

The whole course is really good. The instructor is awesome at teaching concepts. I got to learn a lot of new things.

Thanks Prof Schaub, that was a wonder of a course! Learned so much and still want to proceed :)

Course is amazing and well detailed with different live perspectives.
