Estratégias de controle por modelo de referência de sistemas a eventos discretos Max-plus Lineares

By Carlos Andrey Maia, Ricardo Lüders, Rafael Santos Mendes and Laurent Hardouin

Abstract

Este artigo trata do controle de sistemas a eventos discretos modelados pela álgebra Max-plus. Esta abordagem é usada para descrever processos cuja dinâmica seja caracterizada por retardos no tempo e fenômenos de sincronização. Exemplos típicos desses processos são as linhas de montagem em sistemas de manufatura. O problema de controle estudado está relacionado à estratégia ''just-in-time'' em planejamento da produção. Neste artigo tutorial, diversas estratégias baseadas na abordagem por modelo de referência são apresentadas, exemplificadas e discutidas.<br>This paper deals with the control of discrete event systems modelled by the Max-plus algebra. This approach is used to describe processes whose dynamics are characterized by time delay and synchronization phenomena. Typical examples of these processes are assembly lines in manufacturing systems. The studied control problem is related to the just-in-time strategy for production planning. In this tutorial paper, several strategies based on the model reference control approach are presented, exemplified and discussed
