In this paper, a variable-speed rotary compressor controller was developed by using low-cost high performance digital signal controller. Sensorless control of compressor's interior permanent magnet synchronous motor is obtained using fundamental excitation method. Start-up, rotor alignment, merging, position and speed estimation algorithm was explained. Developed system was tested with a loaded rotary compressor that is the part of a heat-pump system and experimental results were presented.
