Abstract
New method for the determination of blades oscillation parameters is proposed. The approach is based on the analysis of primary transducers signals distortions using nonlinear approximation techniques. Blades oscillations lead to distortions of primary transducer output signal, non-linear approximation techniques allow to determine blade oscillation parameters. The system for the determination of blades oscillation parameters with front-end processing module and succeeding processing on PC is described.
