基于ANSYS APDL二次开发的航电设备的动力学扫频分析，载荷输入条件为交越频率以下为恒定位移，交越频率以上为恒定加速度。我将加速度输入转换为位移输入，将位移和加速度两段输入载荷统一按照位移载荷输入，将位移存入表数组，利用ANSYS APDL自动将扫频范围内的位移载荷存入表数组，并循环加载计算，实现了该工程结构的正弦扫频振动分析。(Kinetic sweep analysis, load input conditions of secondary development based on ANSYS APDL avionics for the crossover frequency less constant displacement, above the crossover frequency is constant acceleration. I will convert the input displacement input acceleration, displacement and acceleration loads unity in accordance with the displacement of the two input load input, the displacement of the array into the table using ANSYS APDL automatically load displacement within the sweep range of the array into the table, and cyclic loading calculated to achieve a swept sine vibration of the project structure.)

利用PHD算法对函数的频率进行估计并画出图形(you can obtain frequency of the function by the PHD algorithm and get the figure)

通信系统基带传输系统中的窗函数法设计滤波器(Communication system baseband transmission system window function design filters)

说明：  基于遗传算法的PID参数整定。由系统的阶跃响应曲线可见，系统是稳定的，且调节时间较短。(PID parameter tuning based on genetic algorithm.)

说明：  基于模糊PID控制下的BUCK电路稳压输出的仿真，并对比了模糊控制和PID控制。(Based on the simulation of BUCK circuit voltage stabilizing output under fuzzy PID control, the fuzzy control and PID control are compared.)

利用matlab求解网络覆盖问题，代码可以直接运行(Network coverage using matlab to solve the problem, the code can be run directly)

This is a tutorial to help you get started in Matlab. To find more details see the very helpful book Mastering MATLAB 6 by Duane Hanselman and Bruce Littlefield. Examples of Matlab code in this pamphlet are in typewriter font like this. As you read through the sections below type and execute in Matlab all of the examples, either at the  command line prompt or in a test program you make called test.m. Longer sections of code are flagged with the characters begin and end. All of the Matlab code between these two
