Résumé:
This paper deals with unknown input estimation for switched linear systems in
an Unknown But Bounded Error (UBBE) framework. Based on a known switching
signal and under the fulfilment of the relative degree property by all the subsystems,
a decoupling method is used to make the state partially affected by the unknown
input. Assuming that the disturbances and the measurement noises are unknown but
bounded with a priori known bounds, lower and upper bounds of the unmeasured
state and unknown input are then computed. A numerical example illustrates the
efficiency of the proposed methodology.
