| Abstract: | This paper analyzes the influence of amplitude and quadrature error of Inductosyn on the measurement accuracy in detail,researches the theory of detecting the two kinds of error,and proposes a multi-position error detection method.Nonlinear equations are linearized through search methods,least-square algorithm is applied to measure amplitude and quadrature errors,and further amplitude and quadrature errors are modified.Finally,experiments show that this updating method of error could improve the accuracy of... |
