Abstract：A method of analyzing the influence of the position deviation of the reading head to suppress the angular deviation is proposed based on multi-reading heads of equal average system. Theoretical analysis and simulation method of the angular deviation introduced by the non- ideal position of reading head are introduced. The harmonic error is separated and the decay rate of error amplitude is obtained. The method is applied to error analysis of the encoder, and the result shows that±0.09″ angular deviation can be introduced by 0.5° position deviation of reading head.
