| Abstract: | In direct torque control system, the stator resistance of asynchronism electro motor, is variable due to the effect of temperature. Consequently, it influence the low speed performance of the system . In order to solve this problem, this paper introduce and analyse the characteristic and arithmetic of ANN, then designs a stator resistance intelligent observer based on BP neutral network and simulink by means of Matlab. With the result of simulation, it has been proved that the neural network resistance observer enjoys a accury. |
