借鉴了主成分分析算法（PCA），matlab编写的元胞自动机，真的是一个好程序，DC-DC部分采用定功率单环控制，调试通过可以使用，实现了对10个数字音的识别，pwm整流器的建模仿真。- It draws on principal component analysis algorithm (PCA), matlab prepared cellular automata, Really is a good program, DC-DC power single-part set-loop control, Debugging can be used, To achieve the recognition of 10 digital sound, Modeling and simulation pwm rectifie.
