Cursusdoelen
The goal of this course is to allow students to design control systems for systems with nonlinear dynamics. These control systems should meet certain stability specifications and provide reasonable robustness. By the end of the course, each student should be able to do the following:
Analyze the qualitative behavior near equilibrium points of nonlinear systems and robots.
Understand the fundamental properties of nonlinear systems (existence and uniqueness, differentiability of solutions and sensitivity, dependence on initial conditions and parameters), and implement these techniques on robotic systems.
Analyze the controllability and observability of nonlinear systems and robotic systems.
Analyze the stability of nonlinear systems.
Design of feedback control systems for nonlinear systems and robots.
