| Abstract: | In this paper,the design method of neural network speed controller for the vector control system of induction motor is introduced.And a new hybrid speed identification method is also proposed, which based on the neural network,combines the open loop estimator and the instantaneous reactive power model reference adaptive system.The simulation results show that the vector control system based on this speed controller and speed estimation has better dynamic and static performance,it solves the instability based on the instantaneous reactive power in the regenerating mode, and has high estimating precision. |
