A new indirect adaptive pole placer for linear MIMO systems

The adaptive pole placement problem, for linear MIMO continuous time systems, is solved using generalized sampled-data hold functions. In the proposed adaptive scheme, persistency of excitation of the controlled system is assured without making assumptions on the existence of special convex sets in which the estimated system parameters belong, or on the coprimeness of the polynomials describing the ARMA model. The a priori knowledge needed to implement the proposed algorithm, is controllability and observability of the system under control, known order, and notion of a set of structural indices of the continuous-time system.
