About this Course

This capstone course is the 3rd and final course of the specialization Advanced Spacecraft Dynamics and Control. It assumes you have completed the prior courses on "Attitude Control with Momentum Exchange Devices" and "Analytical Mechanics for Spacecraft Dynamics".  This project course investigates the dynamics of a complex spacecraft system where there is a rigid hub onto which a hinged panel is attached.  This simulates a spacecraft with a time varying geometry.
First, the three-dimensional kinematics of this system are explored.  Analytical relationships of the body and panel position and velocity states are derived, and the center of mass properties of this system are explored.

Next, a simplified system is used to use Lagrange's equations of motion to predict the dynamical response.  With these differential equations we are then able to apply attitude control torques and investigate the rotational response if the spacecraft hub has a spring-hinged panel attached.  Two open-loop control torque solutions are investigated.  The classical minimum time bang-bang control solution is applied first, illustrating how such a control can yield unwanted panel oscillations.  Finally, a filtered version of the bang-bang control is applied to illustrated how the panel oscillations can be significantly reduced at the cost of a slightly longer nominal maneuver time.

Planar Rotation Control using Bang-Bang and Filtered Control Solutions

In this module we develop the differential equations of motion of the hub-panel spacecraft system that is constrained to rotate about a single axis. Two different open-loop torque solutions are applied to reorient the spacecraft from rest to a new stationary attitude. The impact of filtering a classical bang-bang control solution is investigated by apply a first-order low-pass filter to the control input.

About the Advanced Spacecraft Dynamics and Control Specialization

This Specialization on advanced spacecraft dynamcis and control is intended for experienced spacecraft dynamics and GNC engineers and researchers. It is assumed the viewer has completed the prior spacecraft dynamics specialization already. Through 3 courses we cover the topics of momentum-based attitude dynamics and control, we derive analytical methods to model complex spacecraft systems, and finally conclude with a captstone project course. After this course you will be prepared to model the dynamics of spacecraft systems with time varying components (reacton wheels, CMS, deployable panels, etc.).

Frequently Asked Questions

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:
The course may not offer an audit option. You can try a Free Trial instead, or apply for Financial Aid.
The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
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.
