A new kind of parameter identification of the ship propulsion motor

The paper puts forward a linear induction motor mathematic expression by introducing auxiliary variable method. and build a new kind of least squares parameter estimation algorithm which combine multi-innovation theory and FFRLS with the reset feature, Finally the method is used for system identification of the three-phase asynchronous. The experimental results show that the identification algorithm can well apply input signal contains noise, identification of convergence is rapid, the result error is relatively small, identification effect is good, can achieve accurate identification of induction motor parameters.
