An exact discrete-time transfer-function representation for the analysis and design of discrete/continuous control systems

Discrete/continuous (D/C) control is a modern generalization of contemporary "zero-order-hold" (zoh) type discrete-time control. In this paper, a transfer-function formulation of MIMO discrete/continuous controllers and corresponding, exact "D/C-discretized" MIMO plant models is developed. The results allow control designers to analyze and design D/C controllers using exact, discrete-time transfer-functions and classical block-diagram methods.
