Modelagem e projeto de um sistema de controle supervisório para um processo de lavagem de microplacas

Abstract

This thesis presents the utilization of discrete events systems to the modeling and the project of a supervisory control system for a microplate washing process used in laboratory analysis. The project is based in a local modular approach which exploits the modularity of the plant and the control's specification, avoiding the explosion due to the state combination. The projected control system guarantees that the supervision is nonblocking and that the specifications are met in a minimal restrictive way. The modular architecture provides flexibility and easy implementation. Furthermore, results of simulation are presented, which illustrates the dynamic behavior of the closed loop system.
