DCDC变换器模型,采用双闭环控制，电压PI外环控制输出电压，电流PI内环加快相应速度(Model of a DC-DC converter，the completion of the current loop, double closed loop control scheme of voltage outer loop.)

MATLAB7_0基础教程_清华大学 希望需要的朋友自己看看哦 matlab是我们重要的工具~！(_ Tsinghua University tutorial basic MATLAB7_0 hope to see their own friends required Oh matlab are important tools for us ~!)

with this package,we can perform pitch estimation with different techniques, which is valuable in speech analysis.
