Predictive control with filtering of input and output variables

Abstract

The paper is focused on an implementation of a predictive controller with a colouring filter C in a disturbance model. The filter is often essential for practical applications of predictive control based on transfer function models. It is commonly considered as a design parameter because it has direct effects on closed loop performance. In this paper a computation of predictions for the case with the colouring polynomial is introduced. The computation is based on a particular model of the controlled system in the form of transfer function which is commonly used for description of a range of processes. Performance of closed loop system with and without the colouring polynomial in the disturbance model was compared. © ECMS Valeri M.
