We introduce a new class of high-order sliding mode (HOSM) controllers with improved convergence rate for a single-input uncertain system. The controllers are designed by means of Control Lyapunov Functions (CLF's) and properties of homogeneous systems in the bi-limit. Therefore, the proposed controllers in feedback with the system make the close-loop system homogeneous in the bi-limit. Robustness and convergence rate are improved in comparison with the reported HOSM.
