Abstract

A general transformation that takes linear systems into their regular form, for any relative degree is introduced. A sliding surface where unmatched unknown inputs are attenuated via a reduced order H_∞ control is designed, for the case of relative degree two. By a discontinuous control action, the surface is reached exactly in finite time, guaranteeing the minimization of the unmatched disturbance. Complete state measurements are not necessary.
