建立高精度数学模型的研究

论述了对于电动机驱动系统，如何通过误差评价，不断修正近似数学模型，从而建立起高精度化的数学模型的一种有效方法。

In this paper,an example is given that the mathematical model established originally is not correct.Subsequently,the error between the ambiguous mathematical model and current value of the actual motor systems is evaluated.Finally,on the basis of the error evaluation,we try to propose the mathematical model with higher precision.
