Abstract :
The proposed observer computes an outer approximation of the set of states which are consistent with a given uncertain state space model and some measurements. The uncertainties are modeled by unknown but bounded inputs. A representation of domains by zonotopes (particular polytopes) is used to reduce the computation of state bounds to rather simple matrix operations and to control the wrapping effect.
