| Abstract: | This paper proposes a flux estimate algorithm based on electric current feedback estimater.Thereby,the influence of the parameter variation in an induction motor can be restrained,the alternation of high and low speed flux being unnecessary.For the induction motor with direct torque control,the regulation of speed can be performed in whole speed range.Numerical simulation shows that the algorithm is effective and has practical value in engineering. |
