The course content is good and the quizzes are relevant. 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. 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.

Congratulations!!!

An excellent well structured and advanced high level course.

Themes like as General stability, Nonlinear stability, Langradge stability, Lyapunov stability, Asymptotic stability, Neighborhood are defined. 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.

Thank prof. Schaub for very high quality course. By passing this course, I better understand kind of stabilities. This course provides basis technic for defining nonlinear control law base on Lyapunov function. 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.

Very great course, one only mark is the integral feedback quiz, for the integration problem, the answer required to solve the problem is a bit different from the real answer in which shall be corrected, everything else is great

Excellent teaching from Professor Schaub ! Course has been very well organised and touches on the important aspects of nonlinear control. Looking forward to more courses from you.

Thank you !

Excellent course! Enjoyed it a lot. Learnt a lot as well. Thank you.

works for me.

Bad maintenance of the questionnaires, that in too many cases exhibit questions to be answered with a magic number yielded by a simulation, that happens to be invalid even though the simulation runs perfectly. With no indications about integration intervals or stuff like that, basing the correctness of the answer on the resolution of an unknown number is too much of a lucky issue.

I find a real lack of maintenance effort in the several assignments and questionnaires. Moreover, assignments keep unchanged for years, what reduces uniqueness to the questions and allow the pupils to find the answers across the historic of the discussions.

Having said that, I must admit that the course is rather interesting and professor Mr. Schaub is absolutely, completely superb!!!!!

But please, please, please, if you don't want to mess up an otherwise super interesting course, review the questions and assignments.

Interesting course but the way the course is supported and course work is being assessed needs major reconsideration.
