%X The semiglobally practical stabilization of a class of nonlinear systems with unknown parameters is considered.A Lyapunov function for the overall system is established through a Lyapunov function of the linear part and that of the zero dynamics.A state feedback and a dynamic output feedback are designed respectively to stabilize the system.It also verifies that the controllers are robust as long as the variation of unknown parameters maintains the same relative degree.A simulation (example) shows its effectiveness.
