Abstract：
 This invention relates to nonvelocity sensor permanent-magnet synchro-motor-air conditioning compressor system. It is characterized by that nonvelocity sensor vector control is used for permanent-magnet synchromotor, so, overcoming the shortcoming of the large rotating speed pulsation. At the same time, the torque command current composite control method is used to make further lowering rotating speed pulsation of the motor. It overcomes the problem of unsatability of the system during the procedure of regulating PI regulator parameter in traditional vector control system.
