[en] In the last years the production of electric vehicles has been incentivized in order to achieve a number of objectives, such as the reduction of CO2 pollutants, as well as for the reduction of the pollution in cities with high populations and for the minimization of fuel dependency, among others. In this context, a relevant technological revolution has been produced with the penetration of the electric vehicle, where conventional combustion engines have been substituted by electric machines. The traction electric machine is one of the most relevant elements of this type of vehicle. In order to carry out the control algorithms that govern the electric machine electromagnetic torque productions it is mandatory to precisely determine the angular position of the rotor. Although several solutions can be considered for such angle determination, such as the usage of encoders or the implementation of sensorless control algorithms, up to date resolver sensors are the most widespread options in the automotive industry. In general, the adaptation of the measurement signals provided by the resolver is carried out using resolver-to-digital hardware devices. However and depending on the particular control platform, as it is the case of a rapid control prototyping platform, it can be of high interest to implement such functionalities in a high speed digital device such as an FPGA. This Project has been focused on the modeling and simulation of the resolver-to-digital algorithm using the model based design approach. In order to meet this target, the Matlab/Simulink software has been used, and an adaptation technique based on oversampling and a Phase Locked Loop has been implemented. Once the functionality of this implementation has been verified using standard Simulink blocks, it has been implemented an verified using XilinX System Generator for its future implementation in an FPGA.

[eu] Azken urteotan ibilgailu elektrikoen fabrikazioa bultzatu da zenbait helburu betetzeko, hala nola CO2 isurketak murrizteko, biztanle-kopuru handia duten hirietako kutsadura murrizteko eta erregai fosilekiko gizarteak duen menpekotasuna jaisteko, besteak beste. Alde horretatik, erreboluzio teknologiko garrantzitsua sortu du ibilgailu elektrikoak, non konbustio-motorra motor elektriko batek eta horri eragiten dion potentzia-elektronikak ordezkatu duten. Trakziorako motorra da mota horretako ibilgailuetako elementu nagusietako bat. Beharrezkoa da motorraren posizio angeluarraren ezagutza zehatza, momentu elektromagnetikoa kontrolatzen duten algoritmoak gauzatzeko. Alde horretatik eta posizio angeluarra zehazteko aukera ezberdinak kontsideratzen badira ere, hala nola encoderren edota sensorless kontrolen erabilera, erresolberra de funtzio hori betetzeko erabiltzen den neurgailu erabiliena. Oro har, sentsore horrek gauzatzen duen neurketaren adaptazioa resolver-to-digital izenarekin ezagutzen den gailu hardware baten bidez gauzatzen da. Hala ere eta kontrolerako erabiltzen den plataformaren menpe, prototipatze azkarrerako plataforma batetan adibidez, interesgarria izan daiteke funtzionalitate horiek abiadura azkarreko gailu digital batetan inplementatzea, adibidez FPGA batetan. Proiektu hau resolver-to-digital algoritmoaren modelizazioan eta simulazioan zentratu da, modeloetan oinarritutako diseinua erabiliz. Horretarako, Matlab/Simulink softwarea erabili da, eta gainlaginketan eta PLL motako jarraitzaile batetan oinarritutako teknika inplementatu da. Behin teknika horren funtzionalitatea Simulink-eko bloke estandarren bidez balioztatu ondoren, XilinX System Generator-en bidez inplementatu da algoritmoa, etorkizunean FPGA batetan integratzeko asmoarekin.
