This paper presents a maximum power point track ing (MPPT) control method for high efficient direct methanol fuel cell (DMFC) generation systems via T-S fuzzy model. In detail, we consider a DC/DC boost converter and incremental resistance method to regulate the output power of the DMFC to increase the output power under various conditions. First, the nonlinear boost converter system is represented by the T-S fuzzy model based control. Then, a fuzzy MPPT controller is proposed to achieve the MPPT control, in which the controller gains are obtained by solving linear matrix inequalities (LMIs). Finally, the satisfactory performance is shown from the simulations even under varying fuel cell conditions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
