초록
This paper proposes a new method to reduce the torque ripple in vector controlled inverter fed synchronous motor systems. In three phase voltage source inverter systems, all the three line currents are generally not measured and the currents of two lines are measured through two sensors and two A/D converters. The measured currents may contain some error due to the non-ideality of the current sensors and A/D converters, and the error coefficient of two line currents are not same. As a result, the developed torque contains the torque ripple. The proposed method can eliminate the torque ripple by setting the error coefficient to same value. To verify the proposed method, digital simulations are carried out.
