要求高精度的

In this paper, a new dynamic accuracy theory is developed. It called the theory of the tracing of dynamic measuring error. The total output error is discomposed to the internal units as well as the external noises. And its modeling methods are discussed. Wavelet neural network is an important method in modern signal processes.

近年来 ，国内外不少学者致力于动态测试方法及数据处理方法的研究，取得了一定的成果，但是对动态测试误差分析方法的研究还不够成熟，不能满足现代高精度测试的要求，需要深入研究新的理论和分析方法。

To denoise, the Byes principle can be applied to train the mass sample, and promote the representability of the characteristic vector. The practice proved that the BP neural networks have capacity of error acceptance, and can classify the vehicle samples not trained. The Fast Vehicle Classification system can meet the demand of the high precision classification.

对于测量系统提取中的一定范围中的数据"噪声"，以Bayes法则进行对大量样本先验去除"噪声"，提高了特征向量的代表性，理论与实际证明这样得到的BP网络有强容错能力，识别没有看到过的汽车样本能够达到高精度识别要求。

Stepper motor applications in their daily lives are more important in some occasions, the requirements for high accuracy, this paper is to use Intel's 51 series single-chip three-phase stepper motor to control movement.
