Abstract :
A method is presented to estimate the dynamics of sliding mode control for a class of uncertain system in presence of unmatched parameter variations and external disturbances. The robust sliding plane is constructed from linear matrix inequality (LMI) based on quadratic stability. An estimate of the whole closed-loop dynamics is given. The results are illustrated by numerical example.
