Abstract :
The present technical note studies a class of nonlinear systems with unmatched perturbations. The combination of integral high-order sliding modes with the hierarchical quasi-continuous controller is proposed allowing finite-time exact compensation of unmatched perturbations with semiglobal convergence features for both regulation and tracking.
