Abstract

A discrete control using different possible discretization models of a continuous plant is presented. The different models of the scheme are obtained from a set of different discretizations of a continuous transfer function under a fractional-order-hold of correcting gain β ϵ [-1,1] (β-FROH). The objective is to design a supervisory scheme which is able to find the most appropriate value for the gain β in an intelligent design framework. A tracking performance index evaluates each possible discretization and the scheme chooses the one with the lowest value. Two different methods of adjusting this value are presented and discussed. The first one selects it among a fixed set of possible values, while in the second one the value of β can be updated by adding or subtracting a small quantity. Simulations are presented to show the usefulness of the scheme.
