A function space model and corresponding pulse transfer function matrix of multirate digital control systems are constructed by using function space method and two different lifting techniques. Based on this model, the definitions of zeros and zero directions of the multirate digital control systems are given, and the methods of calculating the zeros and the associate zero directions are presented. By using the concept of zeros and the associate zero directions, the conditions for the asymptotic ripple free trackingoftheplantreferenceinputintheentirecontinuoustimedomain,including both the sample instant and inter sample region, are proposed.
