摘　　要：论述了感应同步器的幅值误差和正交误差对检测精度的影响,研究了检测幅值误差和正交误差的检测与修正,提出了一种多位置检测误差法.通过搜索方法,将非线性方程组进行线性化处理,应用最小二乘法检测幅值误差和正交误差,进而修正幅值误差和正交误差.实验表明,采用该幅值误差和正交误差的检测与修正方法,可以大大提高感应同步器的精度.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 muhi-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 Inductosyn.
