摘要
随着人工神经网络和数字处理技术的发展,从另一角度研究了一种不必增加光栅刻线,仅采用普通刻线的光栅(50刻线 mm),即可实现高精度、高分辨率的光栅测量技术,并用该技术设计了一个测量系统。系统以高速数字信号处理器(DSP)为核心硬件,用单输入单输出模糊小脑神经网络(SISOFCMAC)拟合出光栅信号,再利用FCMAC的泛化能力,实现对光栅信号的连续数字细分,提高光栅测量精度与分辨率。
Along with the development of artificial neural network and DSP technique, a technique that does not gain engraving line of grating and adopts grating of common engraving line (50 line/ mm), to measure grating with high accuracy and resolution was developed. The measuring system uses a high speed digital signal processor (DSP) for the core hardware, and SISO FCMAC neural network to close with grating signal, and FCMAC generalization performance to realize to the grating signal subdivide for increasing measuring accuracy and resolution.
