Course Objective: The course will give the students an in-depth introduction to stability and other analysis techniques for nonlinear systems and prepare them for courses on nonlinear control design (MAE 281B) and adaptive control (MAE 282, alternate years). Students from all departments are welcome.

 

Topics: Existence and uniqueness of solutions of ODEs, sensitivity equations. Stability, direct and converse Lyapunov theorems, LaSalle's theorem, linearization, invariance theorems. Stability of perturbed systems with vanishing and non-vanishing perturbations, input-to-state ability, comparison method. Input-output stability. Perturbation theory and averaging. Singular perturbations. Center manifold theorem.

 

Academic Integrity: Collaboration on homework is encouraged but each student should present his/her own work in the homework solutions they submit. On the final exam, no collaboration is allowed. Students who collaborate on the final exam will not receive a passing grade in the course.
