Course description and aims

This course provides lectures on theory and application of nonlinear and adaptive control systems. Methods of on-line parameter identification and adaptive control for nonlinear systems with uncertain parameters are discussed. To this end, Lyapunov stability theory and Lyapunov functions for general nonlinear systems are examined in the first part of the course.

Student learning outcomes

By the end of this course, students will be able to:
1) Examine existence and uniqueness of solutions of nonlinear differential equations
2) Understand the notion of Lyapunov stability theory and dissipation theory
3) Characterize passivity and nonexpansivity analogous to positive real and bounded real systems
4) Develop adaptive control laws for linear uncertain systems

Keywords

Existence and uniqueness of solutions of differential equations, Lyapunov stability, Lyapunov functions, Lyapunov equations, Dissipativity, Storage functions, Supply rate, passivity and nonexpansivity, positive real and bounded real systems, KYP equations, Normal form representation, Absolute stability theory, Adaptive Control

Competencies that will be developed

✔ Specialist skills Intercultural skills Communication skills Critical thinking skills Practical and/or problem-solving skills

Class flow

At the beginning of each class, some of the important points learned in the previous class are reviewed. Then the main topics for the day are explained in detail. Students are advised to solve exercise problems at home.
