Resumen:
We propose a generalized homogeneous controller for a class of single-input uncertain dynamical system. The controllers are designed by means of Homogeneous Control Lyapunov Functions (HCLF's). The proposed controllers in feedback with the system make the close-loop system homogeneous of some degree. Depending on the selection of the parameters in the control law, the state trajectories reach the origin of the system asymptotically or in finite time. A class of homogeneous discontinuous controllers is also recovered. Furthermore, different discontinuous finite-time controllers with improved convergence rate can be synthesized. © IFAC.
