About the course
Course content
Methods for analysis and design of nonlinear systems, with an emphasis on nonlinear control systems. The course includes: 1) Mathematical models of nonlinear systems, and fundamental differences between the behavior of linear and nonlinear systems. Equilibrium points, limit cycles and general invariant sets. 2) Phase plane analysis, Lyapunov stability, Input-to-state stability, Input-Output stability, and Passivity analysis. 3) Nonlinear control design, including Lyapunov-based control, Energy-based control, Cascaded control, Passivity-based control, Input-Output linearization, Adaptive Control and Backstepping.
