转速环的MATLAB仿真，感觉效果 挺不错的。(MATLAB simulation speed ring, I feel very good results.)

kalman filter main routine can be used to DSGE model and state space model

libev-4.15源码 libev是Marc Lehmann用C写的高性能事件循环库。通过libev，可以灵活地把各种事件组织管理起来，如：时钟、io、信号等。libev在业界内也是广受好评，不少项目都采用它来做底层的事件循环。node.js也是其中之一(libev-4.15 source libev Marc Lehmann is written in C, a high-performance event loop library. By libev, the flexibility to manage the organization of various events, such as: clock, io, signals. libev is also widely acclaimed in the industry, many projects have adopted it as the underlying event loop. node.js is one of them)

felllow 学生 ，无线充电论文，挺好的 ，两篇SCI论文(Felllow student, wireless charging paper, very good, two SCI papers)

一本介绍工程类数学的书籍，包括统计，优化etc.很不错，很基础(1 describes engineering mathematics books, including statistics, optimization etc. Very good, very basic)

学习matlab很好的PPT课件，还有很多经典程序(matlab study)

多径时变信道建模仿真，利用matlab产生单频信号与数字信号经过多径时变信道后的输出信号波(Time-varying multipath channel modeling and simulation, using matlab generate a single frequency signal and digital signal through the multipath time-varying channel output signal after the wave)

关于adrc控制的源代码，需要的朋友可以瞧一瞧(About adrc control of the source code, you need a friend you can take a look)
