Power electronics elements lifetime in BLDCM drives can be affected due to power losses by conduction and switching during their operation. These losses normally arent consider in the design of controller, hence the controller lifetime is reduced or generate early failures. In this work, a fuzzy controller optimization through of PSO algorithm is proposed, this controller design considers the semiconductors temperature and the speed of BLDCM, it allows to increase power electronics lifetime at the same time that the speed desired is achieved. Finally, The Fuzzy-PSO controller results are compared with a PID conventional controller and Fuzzy conventional controller. These results are superior in comparison to conventional controllers since increase the power electronics lifetime and reach the speed set point. Additionally, the co-simulation as a methodology that allows to design, to implement and to validate prototypes in a reliable way. In this co-simulation the power electronics devices, the BLDCM and the controller proposed were designed in Multisim TM and LabVIEW TM from National Instrument (NI).
