Abstract: In the present work, two approaches for the phase current measurement of a permanent magnet synchronous motor (PMSM) were compared. The measured phase current was distorted by glitches, and a software method to eliminate these glitches was necessary. An averaging of samples was carried out, and the experimental results indicated that averaging was essential for further calculations. Moreover, the PMSM operated smoothly, and the difference between the set point and the actual speed was reduced for the full range of loads from the free run up to a full load. The increasing popularity of field-programmable gate array (FPGA) devices has encouraged developments in PMSM controllers using a direct hardware approach and the classic software approach utilizing a digital signal processor unit. In this study, the selected performance of TMS320F2812 and Spartan-3E were compared. This paper proposes an original adaptive correction method for a current transducer.
