Estudo preliminar do controle de dispositivos de estabilização de movimento visando implementação em embarcações da Região Amazônica

Abstract

In the Amazon region, there are several, displacement, semi-displacement and planning vessels operating in typical activities. Motion stabilization technologies in naval systems may provide benefits in performance and onboard experiences, two highly desirable product indicators for consumers due to the competitive characteristics of the sector. The benefits of using naval stabilizer equipment, such as trim tab and interceptor equipment, which in the experiments conducted by Song et al. (2018) achieved a reduction in total resistance of the hull of approximately 8.61%, could contribute to the economic viability of ship, such as its competitiveness and establishment in the Amazon naval industry. Adequate control systems regarding vessel movements are desirable. This application will bring up prospects for boosting cruising speed, lowering operational costs, and enhancing comfort and safety on board. To contribute to this goal, this work aims to review existing technologies and equipment in the naval motion stabilizer sector that can be installed on vessels, focusing on equipment with control systems, such as trim tabs or interceptor systems. Moreover, to demonstrate the functioning of such control systems, a simplified model of an oscillating beam structure was built. The movement of the structure was controlled by a PID controller and, whose implementation technique and code were made available. Through simplified experiments, resembling the ship motion represented by a mass-damper-spring system, the oscillations of the model were reduced through various controller setup. This work can be considered as a preliminary step toward the development of low-cost control systems for vessels employed in the Amazon region.
