No. of bitstreams: 1 Evandro de Carvalho Gomes.pdf: 6042842 bytes, checksum: 26caa437e6eddbd118b3278d1421a757 (MD5) Previous issue date: 2009-09-11 / In this work, we propose to analyze the controller design of a classical dc-dc converter in a different manner. Instead of the traditional mathematics transfer function analysis, we will describe the block diagram of the plant to be controlled using Space-State Averaging, decoupling the states effects one acts each other and designing the controllers individually. With this technique, we can obtain first order transfer function allowing easier synthesis and design of the involved controllers. Outcomes are compared to controllers based on K-factor approach which are entirely applicable in academy and industry environment. / Neste trabalho propomos analisar o projeto de controladores para conversores cc-cc clássicos de uma forma diferente da tradicional análise matemática da função de transferência, descrevendo o diagrama de blocos da planta a ser controlada, desacoplando os efeitos que um estado exerce sobre o outro e projetando os controladores individualmente. Com essa técnica, obtêm-se funções de transferências de primeira ordem o que permite um projeto e síntese mais fácil dos controladores envolvidos. Os resultados são comparados com os controladores baseados na abordagem do fator K, por se tratar de uma abordagem amplamente aplicada no meio acadêmico e industrial.
