To eliminate the influences of changes in parameters on the control strategy during the motor operation,a method based on genetic algorithm is proposed to identify the stator resistance,stator inductance and rotor flux linkage of a salient pole permanent magnet synchronous motor. In the identification process,the current,voltage and rotor angular velocity are sampled from the motor port at first. Then,the electromagnetic torque and salient rate which lead to the sub-rank of identification equations are searched for directly using the genetic algorithm. Finally,the results are calculated by the...
