应用背景如今机器人已经逐渐在社会某些领域崭露头角，无人机、智能车等机器越来越显示出其独有的优势。本设计实现智能小车在跷跷板上保持平衡。关键技术智能小车采用单片机为MCU，外接了轮子，马达等必要器件，采用C语言编程，能够完成上跷跷板、在跷跷板上保持平衡等的功能。

谭甜源老师编写的基于PSCAD的 电力电子仿真，能帮助读者方便使用PSCAD来学习电力电子。(Power CAD simulation based on PSCAD written by Teacher Tan Tianyuan can help readers to use PSCAD to learn power electronics.)

此程序能够计算一个数据集的熵和基于某个属性的熵-this procedure to calculate a data set based on the entropy and the entropy of a particular attribute

Distributed Sensor Networks part1

说明：  基于UDP的单片机远程示波器，测试平台ESP8266完美通过，最多支持1000hz刷新率(UDP-based SCM remote oscilloscope, the test platform ESP8266 passes perfectly and supports refresh rate of up to 1000 Hz)

整个软件是MATLAB环境下的控制系统仿真，用户输入控制系统前项通道传递函数和反馈通道传递函数以及性能指标，绘制出校正前开环系统的BODE图，并给出稳定裕量和对应的频率。 判断该用哪种校正装置。给出校正装置的传递函数，在一幅图上显示校正后系统的BODE图。给出校正后系统的性能指标。(The software is the MATLAB environment control system simulation, user input control system before the entry channel transfer function and the feedback channel transfer function and performance indicators, drawing out the correction before the open-loop system of the BODE diagram, and gives a stable margin and the corresponding frequency of . Determine the correct device to use which. Calibration device transfer function is given in a map display system BODE diagram after correction. Corrected performance of the system are given index.)

Design of DC DC Boost converter

python神经网络书中的代码，非常使用的学习资料(the code in<python nerual net>, this is trully useful)

A rapid development framework for the development of a set of ThinkPHP5.0.3 based on open source PHP, DophinPHP speed, the ultimate minimalist, adhering to the concept of development, for the development of integrated data - role-based permission management mechanism, integrating a variety of flexible and rapid construction tools, can facilitate the rapid expansion of the module, plug-in, hook, packet. Unified modules, plug-ins, hooks, versions and dependencies between packets, further reducing the code and data redundancy, so that developers can quickly build their own applications.
