Résumé:
This paper addresses the problem of interval observer design for unknown input estimation in Linear
Time-Invariant (LTI) systems. Although the problem of unknown input estimation has been widely
studied in the literature, the design of joint state and unknown input observers has not been considered
within a set-membership context. While conventional interval observers could be used to propagate,
with some additional conservatism, unknown inputs by considering them as disturbances, the proposed
approach allows their estimation. Under the assumption that the measurement noise and the disturbances
are bounded, lower and upper bounds for the unmeasured state and unknown inputs are computed.
Numerical simulations are presented to show the efficiency of the proposed approach.
