Xiaoting Ye, Qingchun Zhang, Tao Zhang · 2011
According to the mathematic model of induction motor, a new method of speed estimation based on the neural network was presented in this paper. Based on the traditional adaptive system, the neural network replaces the original organization used in the speed-sensorless vector control system. A kind of new method of speed estimation based on the neural network, and the structure and learning algorithm of the neural network were proposed. The designed method has the advantages of simple structure and good robustness. The simulation result showed that the new method could accurately track the variation of the motor speed and had good performance.
