2017 - Atual: Sistemas Dinâmicos Sujeitos à Incertezas: Modelagem, Filtragem, Controle e Aplicações

Devido a problemas de caracterização de incertezas ou complexidade de diversos sistemas, os modelos estocásticos têm tido um papel fundamental no estudo de sistemas reais. Este projeto de pesquisa tem como objetivo utilizar métodos estocásticos avançados e robustos para solucionar problemas relevantes de modelagem, estimação e controle associados a sistemas sujeitos à incertezas. O projeto contempla diversas questões teóricas e aplicações no tema que denominaremos de sistemas dinâmicos multi-modelo estocásticos, que inclui a classe dos processos de Markov determinísticos por partes (PMDP) e os sistemas com saltos Markovianos (SSM).
