Abstract

Abstract:

To solve the problem of rotor position detection for brushless DC motor used in electric power steering (EPS) system, this paper introduces a new decoding method for reluctance cosine resolver. This method uses a new resolver digital converter (RDC) AD2S1210 to achieve resolver output signalis decoded,and designed a chip peripheral circuit, excitation signal buffer circuits and a digital interface circuit. After demodulation, the demodulated signal is output via the serial output mode, then sending out the angular position information into the microcontroller dsPIC30F6010, and the information of rotor position is read from the EEPROM memory data table in the microcontroller. Finally, three square wave signals with a difference of 120 degrees between each other is obtained, which issimilar to the waves produced by three Halls, realizing the conversion from analog to digital. Finally, this scheme was used to detect rotor position of brushless DC motor in automotive electric power steering (EPS) system, and verify the feasibility of the method.
