Applied ARMA process as current filter for VFD application

The paper proposes the application of ARMA time series model to VFD (variable frquency drive) current filtering. The problem is examined on measured currents of an induction motor driven by comercial frequency converter. The currents are filtered by adaptive ARMA time series model structured as a band-pass filter. The adaptation is realized through recursive least squares regression.
