由于系统因素之间关系非常复杂，特别是其表面现象及变化的随机性、模糊性和灰色性，使人们在观察、分析、预测和决策时得不到足够的信息，找不到主要矛盾，从而给复杂系统的系统分析带来困难。这就需要灰色关联分析。(Because the system is very complex relationship between factors, especially changes in the surface phenomena and random, fuzzy and gray so that people in the observation, analysis, forecasting and decision-making can not get enough information, can not find the main contradictions thus to the complex system of systems analysis difficult. This requires gray relational analysis.)

本论文利用TI公司的16位定点DSP芯片TMS320VC5416-160的硬件、软件结构和特性实现了数字滤波器的设计。深入研究了DSP芯片的硬件开发技术和软件编程技术及调试技巧 在MATLAB环境下,利用MATLAB语言编写程序对IIR滤波器进行仿真并得到滤波器的系数 关于matlab与DSP等。(In this paper, the use of TI' s 16-bit fixed-point DSP chip TMS320VC5416-160 hardware, software structure and characteristics of a digital filter design. In-depth study of the DSP chip technology hardware and software programming and debugging skills in the MATLAB environment, using MATLAB programming language for simulation of the IIR filter and the filter coefficient matlab and DSP and so on.)

说明：  实现了系统辨识的算法，Matlab实现了产生一均值为0，方差为1的噪声，给出系统辨识的效果。(To achieve the system identification algorithm, Matlab realized generated a mean 0 and variance of a noise, the effect of system identification is given.)
