Abstract: We study here the problem of robust and perfect tracking for discrete-time linear systems. By robust and perfect tracking we mean the ability of a controller to track a given reference signal with arbitrarily small settling time in the face of external disturbances and initial conditions. A set of necessary and sufficient conditions under which the proposed problem is solvable are obtained and, under these conditions, constructive algorithms are given that yield required solutions. As is general to discrete-time systems, the solvability conditions to the above problem are quite restrictive. To relax these conditions, we propose an almost perfect tracking scheme, which is capable of tracking references precisely after certain initial steps.
