Learning outcomes

After successful completion of the course, students are able to

• understand and apply the mathematical principles and methods to describe and analyze nonlinear systems.
• apply Lyapunov theory to analyze stability and devise nonlinear control strategies such as integrator backstepping, PD control and computed torque.
• utilize singular perturbation methods to reduced-order models systematically.
• develop nonlinear control schemes based on differential-geometric and differential-algebraic methods such as differential flatness or exact input-state linearization.
