Schedule: Tuesday, Thursday 4:30pm-5:48pm 139 Caldwell
Labs .

Registered students may access all the additional information on the
course there, including notes, homework sets, solutions, and the update
syllabus.
Course Goals:
To give a broad (although necessarily incomplete) overview of adaptive
control for linear and nonlinear systems. The focus of the course is not on giving a painfully
detailed description of several techniques, rather on
introducing fundamental
concepts and
issues in the analysis and design of adaptive control systems.
Course description:
Adaptive control for linear and nonlinear systems. Adaptive observers.
Model reference adaptive control. Convergence and stability of adaptive
systems. Robustness issues and robust redesign. Manifolds of slow
adaptation, and two-time scale analysis. Adaptive backstepping design
for nonlinear systems. Applications.
