An anti-windup scheme for proportional-integral-derivative controllers is presented. The approach is based on the combined use of back-calculation and conditional integration antiwindup techniques. In this way, the disadvantages that can hinder previously proposed strategies are overcome. Specifically, the method can guarantee a satisfactory performance for processes with different normalised dead times, without the tuning of additional parameters being required. Therefore, considering its simplicity, it is highly suitable for implementation in industrial regulators.

Abstract
An anti-windup scheme for proportional-integral-derivative controllers is presented. The approach is based on the combined use of back-calculation and conditional integration antiwindup techniques. In this way, the disadvantages that can hinder previously proposed strategies are overcome. Specifically, the method can guarantee a satisfactory performance for processes with different normalised dead times, without the tuning of additional parameters being required. Therefore, considering its simplicity, it is highly suitable for implementation in industrial regulators.File in questo prodotto:
