Interior permanent magnet synchronous motors (IPMSMs) are controlled by either a rotor position sensor or a sensorless control method, which enables highly efficient operation. The voltage-current phase difference control method is a sensorless control method that offers low cost and a simple control system, which is based on V/f control. However, speed ripple occurs under a fluctuating load because...
This paper proposes speed ripple reduction for an interior permanent-magnet synchronous motor (IPMSM) controlling phase difference between the armature voltage and current. The IPMSMs are controlled with a rotor position sensor or by a sensorless control method. Voltage-current phase difference control is one of the sensorless drives with low cost and simple structure. However, if the load varies...
