Brief course outline:
1. Mathematical background.
2. Fundamental properties of dynamical systems:
existence and uniqueness of solutions,
continuous dependence on initial conditions and parameters, comparison
principles.
3. Stability analysis: Lyapunov stability of autonomous and
nonautonomous
systems, LaSalle's invariance principle, converse Lyapunov theorems,
stability of feedback systems, effects of perturbations.
4. Systems with inputs and outputs: input-to-state stability and related
notions, Lyapunov characterizations.
5. Nonlinear control: control Lyapunov functions, universal formulas
for feedback stabilization and disturbance attenuation.
6. Advanced topics (time permitting): center manifold theorem, averaging,
singular perturbations.
