A Hybrid Rotate Speed Identification Method Based on Reactive Power of Induction Motor

More Information
  • In view of the problem of slow convergence of rotate speed identification method of Model Referencing Adaptive System(MRAS) based on reactive power in dynamic process, the paper proposed a hybrid rotate speed identification method based on reactive power, namely combining direct calculation method with MRAS rotate speed identification method. The experimental results showed that the method not only has fast following ability of direct calculation method, but also has strong anti-interference ability of MRAS rotate speed identification method. Meanwhile, the method has simple algorithm and less motor parameters, which is easily realized in engineering.
