| Abstract |
A sensorless control of a PM synchronous motor for
single piston rotary compressor is presented. The rotor position
is estimated from the d-axis and q-axis current errors between
the real system and motor model of the position estimator. The
torque pulsation of the single piston rotary compressor is
compensated to reduce the speed ripples as well as mechanical
vibrations. Proposed sensorless drive provides low speed
operation of the compressor for energy savings and low
mechanical noises. It also gives high speeds operation by flux
weakening control for rapid air-cooling and heating of the heat
pump air-conditioners. |
