A new nonlinear integral sliding mode control (ISMC) algorithm for singularly perturbed multiple-inputs and multiple-outputs (MIMO) systems subject to matched and unmatched uncertainties is proposed. The circumstance of fast sensor dynamics in series with the plant exemplifies the results. Using pri...
