A New Approach for Calibration of Sinusoidal Encoder Signals

Abstract:

Against to the multi-roots problem existed in Heydemann method for calibration of sinusoidal signals, a new approach containing two procedures is proposed. Firstly, the dc offsets and amplitude deviations of sinusodial signals were estimated by two observers separately. Then, to accept the non-orthogonal phase shift in the sinusodial signals, a simple Heydemann method with only two variables was adopted. Simulation results show that this method is feasible, and can converge to the origin with high accuracy. This method will show great values in the field of calibration of sinusoidal encoder signals.
