Output error identification for multi-input multi-output systems with bounded disturbances

In this paper, we present the adaptation of an Optimal Bounding Ellipsoid (OBE) type algorithm for output error systems with unknown but bounded disturbances. Two identification algorithms are derived in a multi-input multi-output context and the paper proposed stability and convergence analysis. An iterative scheme is introduced and simulation are performed, showing the excellent performance of the proposed approach.
