Various approaches to solving an industrially motivated control problem: Software implementation and simulation

Abstract

The main aim of this paper is to present various approaches to solving an industrially motivated control problem, especially from the viewpoint of implementation of control algorithms into the Matlab and Pascal environment. The motivation and basic conditions of the application have been based on real technical assignment of a manufacturer of aluminium-based rolled products and packaging materials. The primary part of the work deals with selected digital self-tuning controllers where the applied methods comprise a polynomial approach to discrete-time control design and recursive least-squares identification algorithm LDDIF. Subsequently, two alternative approaches were analyzed, namely control using continuous-time regulator with fixed parameters and usage of delta approach in self-tuning control.
