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.
