摘要
论述了利用长定子同步电机的齿槽检测信号与线性插值法结合来提高直线同步电机动子位置检测精度的方法。分析了这种方法的误差,给出了实现线性插值的2种算法、实现的方案、仿真与实验结果。
The method is forwarded to improve the detection accuracy of rotor position in linear synchronous motor in use of teeth-slot detecting signals and linear interpolation algorithm of long stator synchronous motor. Tolerances are analyzed. The two algorithms torealize linear interpolation, the solutions along with the simulation and test results are given.
