摘　　要：在对二相步进电机转矩正弦曲线的非理想性分析的基础上,提出了一种实现高精度细分的插值修正算法;算法包括有限标定、FIR滤波器细分插值、正弦修正三部分;并对算法用Matlab进行了建模仿真,分析了细分转矩误差,结果表明该算法可以达到非常高的细分精度,突破了传统细分精度的限制。Based on the non- ideal analysis of the sinusoidal torque of the two-winding stepping motor, the article proposes an interpolation and correction method to achieve high precise micro-stepping. The algorithm includes three main parts： calibration, FIRinterpolation and sinusoidal correction. Modeling and simulation of it is established in Matlab, and the simulation result shows this method can help to achieve much higher precise micro-stepping to breakthrough the limits of traditional method.
