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 ...

By expressing transfer functions in normalized form, the units of the poles and zeros and s can be either s −1 or Hz, but must be the same. Usually, s is in units of s −1, but can be in Hz if the z i ...
