ISBN 978-303091884-2978-303091884-2http://hdl.handle.net/10198/24681This article presents a comparison between a common type III controller and one based on a brain emotional learning paradigm (BELBIC) parameterized using a particle swarm optimization algorithm (PSO). Both strategies were evaluated regarding the set-point accuracy, disturbances rejection ability and control effort of a DC-DC buck converter. The simulation results suggests that, when compared to the common controller, the BELBIC leads to an increase in both set-point tracking and disturbances rejection ability while reducing the dynamics of the control signal.engOptimisationBELBICBuck converterPSOconference paper10.1007/978-3-030-91885-9_25
