A study on the convenient tuning of fractional-order hold
(FROH) electronic devices for digital control systems is
presented. When certain constraints are fulfilled, this
study assures in advance the attainment of inverse stable
discrete plants, when the process to be digitally controlled
is described as a second order plant or as a first order
plant with time delay, and the use of a zero-order hold
(ZOH) fails to do so.
