Abstract |
In order to improve the parameter precision of induction motor in identification at standstill, a novelmethod by adaptive compensation of dead-time effect in inverter control is proposed. Proportionalresonant controller, phase locked loop and the feature of dead-time effect are implemented toadaptively compensate the dead-time effect of current and to relieve the voltage wave distortion. Thenonlinear influence of dead-time effect in direct current measurement is also relieved. Theexperimental results show the proposed method can reduce the harmonics of current and voltage8.92\% and 7.65\% separately. The amplitude and phase of voltage are also compensated. Thefluctuation of voltage amplitude is less than uncompensated one. It is validated that the proposedmethod can improve the measurement precision of resistance and inductance. |
