ROBUST H∞ TRACKING CONTROLLER FOR LINEAR DELAY-DIFFERENTIAL SYSTEMS WITH TIME-VARYING UNCERTAINTIES

RésuméIn this note, the problem of robust tracking and model following for a class of uncertain time delay systems is addressed. We provide, in particular, necessary and sufficient conditions for the existence of robust H∞ memoryless tracking controller. Furthermore, a constructive and easily implementable procedure is detailed. In the last section, performances and efficiency are clearly shown through numerical simulations.
