Real-time fractional order system identification using recursive least squares method
Keywords:fractional order system, identification system, recursive least squares (RLS) technique, Charef approximation method, Grünwald numerical approximation
In this paper, we address the problem of fractional order systems real-time identification based on recursive least squares technique. The fractional order model is approximated using the Charef Singularity function method and Grünwald numerical approximation for fractional order integral and derivative. We show by numerical simulation example that the identified model represents the original system efficiently.
