Abstract

For an estimation based multiple model switched adaptive control (EMMSAC) algorithm controlling a MIMO minimal LTI plant, l_p, 1 Â¿ p Â¿ Â¿ bounds on the gain from the input and output disturbances to the internal signals are obtained which are invariant to the number of models in the plant model set. For a compact uncertainty set it is shown that a realisable EMMSAC algorithm achieves robust stability for any plant within the uncertainty set.
