Description
Summary:This article gives the detailed elaboration of the application of on-line parameter identification of induction motor based on RLS algorithm. Using the application recursion method of least square carries on the parameter identification can simplify the two-dimensional model, avoid the two-dimensional matrix inversion operation question, and reduce the computation load. Solve the Butterworth digital filtering equation of state with the improved Euler numerical solution, figuring out the signal first derivative value and second derivative value in the meantime, which has avoided the influence of derivative discretization error, increased the operation precision. According to the massive simulations and experiments in view of the different power's electrical machinery studies, the experimental result has confirmed its good stability, consistency and accuracy.
