Abstract

This manuscript tackles the regulation problem of linear time invariant systems with unmatched perturbations. A high order sliding mode observer is used allowing theoretically exact state and perturbation estimation. A compensation control approach based on the identified perturbation values is proposed ensuring exact regulation of the unmatched states. A simulation example shows the feasibility of this approach.
