Abstract :
A sensorlesss vector control system of PMSM compressor is presented in this paper. By calculating the magnetic flux linkage, the position of magnetic pole and the speed of the compressor are estimated. To realize the low cost sensorless control, an 8-bit high performance microcontroller-XC886 is used. Phase currents measurement based on shunt resistors in lower legs is adopted to simplify the circuit design. The effectiveness and validity of the proposed scheme are confirmed by experiment results.
