| 英文摘要: |
| Rotor time constant is an important parameter for the indirect field orientated control of induction motor. Incorrect rotor time constant value will cause the flux observer generating a wrong angular orientation of the rotor field. A new approach serves for rotor time constant on-line adaptation by setting the stator current to be zero for a short period. A smooth corrector is designed to prevent abnormal detection result from making adaptation. Impact of zero current duration on detection error and rotor speed is analyzed by experiments. |
