Offset error of a motor-current sensor varies during motor drive and increases torque ripple. To maintain torque at a high quality, on-line methods for compensating that offset error are required. Accordingly, two methods for compensating offset error by using the DC-voltage components included in phase-voltage commands are proposed and evaluated by experiments and simulation respectively. The evaluation...
This paper presents a method for reducing a motor torque ripple resulting from a motor phase current sensor offset error for motor drive applications such as a hybrid electric vehicle. The proposed method estimates the motor phase current sensor offset error on the basis of the direct voltage value included in the voltage source inverter output voltage reference value calculated by a discrete Fourier...
