Sistema de controle da máquina da Corveta Barroso: o aprimoramento do subsistema de ar comprimido do navio

Abstract

Control systems have evolved with computational techniques. Simultaneously controlling multiple variables in multiple states has become primarily dependent on the storage and processing capacity of digital computers. That said, this work presents the implementation of both analog and digital control in the Compressed Air subsystem of the Corveta Barroso, aiming to provide better control of the pressure delivered to the main users. Initially, the concepts of each control are described, and the key technological advances that enabled the shift in control techniques are elucidated. Next, a model for the Ship's Compressed Air system is proposed, taking into account the users most sensitive to pressure variations (Main Engines, Auxiliary Engines, and Gas Turbine). By examining both types of control, the advantages and disadvantages of each will be discussed, along with the presentation of results from the proposed model.
