说明：  基于FPGA设计的串口发送及接收程序，波特率可调(FPGA - based serial port sending and receiving)

大跨悬索桥主缆空间找形程序，通过matlab输入初始参数，程序自动搜索主缆与吊索交点位置，吊索荷载等(The main cable shape finding program of large span suspension bridge)

：对全桥型逆变器的滑模控制方案进行了分析，包括建 立系统的变结构模型、选择滑模切换线和确定控制作用，给 出可到达条件及滑模存在区域等。着重讨论了在实际电路设 计中选择开关面系数和开关频率的原则，并且给出相应的设 计程序。(A sliding mode control scheme for the full bridge buck inverter was analyzed, including modeling the variable structure system, selecting the switching line and control law, and deriving reaching conditions and sliding domain. The criterions of selecting switching surface coefficients and switching frequency for the practical implementation were considered and the corresponding design procedure was presented.)

说明：  核极限学习机，引入核函数解决ELM求解问题，一旦参数选定，结果就稳定下来，不再混入随机。在原来版本上加入自己理解改写，使得代码更容易理解。((Kernel extreme learning machine, kernel function is applied to deal with ELM to solve the problem, once the parameters selected, the result is stabilized, not randomly in the original version on becoming a member of their understanding, makes the code easier to understand))

本人收集到的一些二阶锥优化和凸优化的资料，拿出来共享给大家，希望有用！(I collected some of the second-order cone optimization and convex optimization information out for everyone to share the hope that useful!)

AD9854允许输出的信号频率高达150MHZ，而数字调制输出频率可达100MHZ。通过内部高速比较器正弦波转换为方波输出，可用作方便的时钟发生器。(AD9854 allows the output signal frequency up to 150MHZ, and digital modulation output frequency up to 100MHZ. Through an internal high-speed comparator is converted to square wave sine wave output, the clock generator can be used as a convenience.)

Tesseral 2D正演模拟培训讲义，包括详细的Tesseral 2D使用说明和应用样例(The tesseral 2D forward modeling training handouts, instructions for use and application examples, including detailed Tesseral 2D)

解决全局变量在编程时遇到的疑惑，值得一看。有很好的参考价值。(To resolve global variables encountered in the programming of doubt, worth a visit. Have a very good reference value.)

这个文档供大家参考，有什么意见可以积极提出，我希望和大家一起学习！(this document for reference, what advice can be positive, and I hope that we will study together!)
