【Abstract】 In order to improve performance of DTC, the observing precision of the parameter observer must be high, a new adaptive parameter observer is proposed. With this observer, the stator flux , the stator resistance and rotor resistance which vary with motor temperature, are identified simultaneously and the speed can be also observed. The robustness to parameter variations and good performance are fully verified by the simulations.更多还原
