Controlo Difuso com Modo Deslizante

Nesta dissertação propõe-se o desenvolvimento de metodologias de controlo difuso que exploram o conceito de modo deslizante, com o objetivo de construir uma arquitetura, que permita proporcionar um sistema de controlo adequado em termos de desempenho e robustez. As principais contribuições incluem a implementação de um controlador com inferência de Mamdani com modo deslizante, com superfície deslizante do tipo Proporcional-Derivitativo (PD) e, subsequentemente, do tipo Proporcional-Integral-Derivitativo (PID). O desempenho de cada um destes controladores foi avaliado e comparado com o controlador PID clássico, o controlador PID difuso com inferência de Mamdani e com o controlador convencional por modo deslizante. Foram realizados testes de simulação e, posteriormente, testes experimentais no processo didático AMIRA DTS 200, constituído por três vasos comunicantes. Os resultados obtidos comprovaram o bom desempenho dos controladores de Mamdani com modo deslizante, apresentando uma superfície deslizante do tipo PD e PID, validados através de testes no processo real
