Dissertação (Mestrado em Engenharia) - Universidade Federal de Goiás, Goiânia, 2010.http://repositorio.bc.ufg.br/tede/handle/tde/957This work presents the application of control techniques to drive single-phase induction motors with the aim of improving the performance of cooling systems. The control system is based on Fuzzy Logic and is applied to a three-phase PWM inverter adapted to drive singlephase motors with volts per hertz technique. The main feature of the work is to control the temperature of the cooling system driven by a hermetic compressor using variable speed. A commercial milk cooling system is used to obtain the results.application/pdfAcesso AbertoEficiência EnergéticaControlador NebulosoCompressor HerméticoResfriamento de LeiteEfficiencyFuzzy ControllerHermetic CompressorMilk Cooling1.Eficiência energética 2.Controlador nebuloso 3.Compressor hermético 4.Resfriamento de leiteCNPQ::ENGENHARIAS::ENGENHARIA ELETRICADissertação
