Retrospective cost adaptive control for nonminimum-phase discrete-time systems, part 1: The ideal controller and error system
We present a direct adaptive controller for discrete-time (and thus sampled-data) systems that are possibly nonminimum phase. The adaptive control algorithm requires limited model ...
