A variable structure control system for output tracking in the presence of a class of mismatched uncertainty is studied in this paper. For the mismatched uncertainty, we use an unknown input observer to estimate the states and then apply the VSS control methodology to attain asymptotic output tracking for an arbitrary desired trajectory. The robustness of the VSS control system in the presence of mismatched uncertainty is analyzed using the quadratic stability approach.
