title = "FPGA based signal injection sensorless control of SMPMSM using Delta-Sigma A/D conversion",
abstract = "This paper presents an FPGA based sensorless controller for Surface Mounted Permanent Magnet Synchronous Machines (SMPMSM). The alternating voltage injection method is adopted and the high frequency current responses are measured by Delta-Sigma Modulator. Through suitable design of the low pass decimation filters, this paper realizes a high performance high frequency (HF) injection sensorless control which needs lower HF current response and introduces lower acoustic noises. The paper focuses on the analysis of Delta-Sigma Modulator and the design of SincK filters. The whole control system is implemented in a single FPGA chip. Experimental results demonstrate that the FPGA based sensorless controller using Delta-Sigma modulator has better performance than sensorless control using conventional A/D converter.",
