Abstract
We consider adaptive stabilization for a class of nonlinear second-order systems. Interpreting the system states as position and velocity, the system is assumed to have unknown, position-dependent damping and stiffness. Lyapunov methods are used to prove global convergence of the adaptive controller. For illustration, the controller is used to stabilize the Van der Pol limit cycle as well as the multiple equilibria of the Duffing oscillator
