单片机制作的PLC逻辑可编程控制器，大家可以下载看看，是个开源项目(Produced single-chip programmable logic controller PLC, you can download to see is a open source project)

说明：  使用STM32f103编程实例工程，有ADC、DMA、USART、TIMER、GPIO等编程讲解(STM32f103 programming example project, ADC, DMA, USART, TIMER, GPIO programming explanation)

APD，雪崩放大器。可以将光信号转变成电信号，用于光通信解调当中(APD, avalanche amplifier. Optical signals can be converted into electrical signals for optical communication demodulation.)

本文以第一视角讲述了移植FATFS文件系统的过程。其中遇到的困难，解决方案的寻找，原理的讲解，都能带给人许多启发(This paper describes the process of transplanting FATFS file system from the first perspective. The difficulties encountered, the search for solutions, and the explanation of the principles can give people a lot of inspiration.)

文以永磁同步电机为对象，采用矢量控制方案，首先我们研究了基于PI 的控制算法，在仿真基础上指出了PI 算法存在的一些不足。 在此基础上我们研究了基于扩张状态观测器（ESO）前馈补偿和线性比例反馈控制的永磁同步电机速度环控制算法， (Taking PMSM as the controlled plant, this paper studies the control system based on vector control, first, the servo control scheme based on PI control law is studied. Some limitations of PI based control scheme are pointed out. )
