“…Then a new thrust allocation is performed, considering the saturated thrusters as part of the external forces. This method can be seen in Arditti et al (2015) and Van Daalen et al (2011).…”

“…A significant increase in the complexity of the problem was introduced by considering the saturation of the thrusters, which leads to cases where it is not possible to generate the forces required by the control system. Different solutions were proposed to this problem: The reallocation procedure as described in Arditti et al (2015) keeps the saturated thruster at its azimuth angle and maximum force, and a new allocation problem is solved without the saturated thruster and considering the forces developed by it as an external force. The addition of the errors in the required force constraints to the objective function (in order to minimize the errors) is presented in Arditti et al (2014).…”

“…Computational Fluid Dynamics (CFD) (Cozijn and Hallmann 2012) and model based (Arditti and Tannuri 2012) tests show that hydrodynamic interactions can drastically influence the net thrust. The work presented in Arditti et al (2014) and Arditti et al (2015), with some simplifications in the representation of hydrodynamic interaction, illustrates that by considering these phenomena in the thrust allocation higher reliability and minimization of power consumption can be achieved.…”

“…2) Providing a robust approach for the situation in which it is not possible to generate the required forces. Arditti et al (2015) provides a solution for this problem, however with the need to perform multiple reallocations, which is not efficient. Johansen, Fossen, and Berge (2004) provides an efficient solution for the reallocation problem, however this method is not yet tested in thrust allocation problems considering hydrodynamic interactions.…”

“…The most important definition to be made is how to represent the interaction effects within the thrust allocation process. When considering only simple cases, such as thruster-hull interaction, it has been made with efficiency functions, more specifically polar plots of the efficiency (Arditti et al 2015).…”

Ao meu orientador, Prof. Dr. Eduardo Aoun Tannuri, com quem trabalho em alocação de empuxo desde 2010. Durante toda essa trajetória sempre me apoiou, incentivou e esteve disposto a ajudar, desde discussões técnicas até questões pessoais. Além de dividir comigo seu vasto conhecimento na área de controle de embarcações, foi de extrema importância na análise e preparação dos trabalhos publicados. Não obstante sou extremamente grato pela confiança depositada ao permitir que eu cursasse o mestrado enquanto trabalhava. A Hans Cozijn e Ed van Daalen do Maritime Research Institute Netherlands (MARIN) pelo apoio nas publicações realizadas durante o mestrado. Ao Prof. Dr. Thiago de Castro Martins pelas enriquecedoras discussões sobre otimização. Aos colegas do TPN, Felipe Lopes de Souza com quem cursei matérias do mestrado e sempre se mostrou interessado em discutir o problema de alocação de empuxo, e André S. S. Ianagui com quem tive a oportunidade de apresentar no IFAC-CAMS 2018. Finalmente, à minha família brasileira e holandesa pelo incentivo e altruísmo, pois realizei boa parte das atividades do mestrado no meu tempo com eles.
