TLDR
One of the earlier techniques of speed measurement is compared with the proposed waveform sampling technique by estimating the speed of turbine-generator unit model under steady-state and transient conditions.Abstract:
A method of digital angular speed measurement based on waveform sampling utilizing an orthogonal pair of sinusoids is proposed in this paper. Details of the derivation and implementation of the technique are described. One of the earlier techniques of speed measurement is compared with the proposed waveform sampling technique by estimating the speed of turbine-generator unit model under steady-state and transient conditions.read more
