Abstract

This paper considers the control problem for self-servowriting indisk drives where information propagation occurs in twoindependent directions, i.e.\ time and track number respectively.The resulting state-space model is not of the~well known Roesseror~Fornasini-Marchesini types and hence cannot be analyzed usingthe~theory associated with these 2D discrete linear systemsmodels. Instead, it is shown here that it can written as adiscrete linear repetitive process state-space model which is anextension of those already encountered and for which it isnecessary to develop new tools for stability analysis andcontroller design. Finally, the application of these isillustrated by a simulation example using industry supplied data.
