台车倒立摆模型的滑膜变结构控制器算法（四阶对象）。(Car inverted pendulum model of synovial variable structure controller algorithm (fourth-order objects).)

信号与系统软件实验工具箱，本系统包括七个实验，分别是：信号的时域基本运算、连续信号的卷积与连续时间系统的时域分析、离散信号的卷积与离散时间系统的时域分析、信号的频域分析、连续信号的采样与恢复、系统的频域分析、信号的幅度调制与解调。为了加强学生的计算机编程能力和应用能力，所有实验均提供设计性实验内容，让学生参与编程。本系统既可作为教师教学的实验演示，又可作为学生动手实验的实验系统。(Signals and Systems Software experimental toolbox, the system includes seven experiments, namely: basic operations signals in time domain, the convolution of continuous signals and continuous-time system time domain analysis, convolution of discrete signals and discrete-time systems when domain analysis, frequency domain signal analysis, continuous signal sampling and recovery, system frequency domain analysis, signal amplitude modulation and demodulation. In order to strengthen the student s computer programming skills and ability to provide all the experiments were designed experiment content, allowing students to participate in programming. This system can be used as experimental demonstration of teaching, but also as a student hands-on experiments the experimental system.)

Different type of matlab codes and modelsim based codes have been attached

主要是lasso和lars的MATLAB程序，其中含有例子和数据。(Mainly lasso and lars MATLAB program, which contains examples and data.)

窗函数法设计一个数字带通FIR滤波器，进行逐步线性回归，意信号卷积的运算,并且绘制图象。( A window function design FIR digital band-pass filter, Stepwise linear regression, Convolution operation is intended to signal and image rendering.)

卷积码的matlab结构图，很实用，很简洁，欢迎大家下载(Convolution matlab code structure is very useful, very simple, welcome you to download)

SMC for Boost Converter

说明：  fft算法，fft与dft算法的比较，并有详细的文档说明。(fft algorithm, fft compared with the dft algorithm and a detailed description of the document.)

现需要在高度为600~700KM范围内，回归周期为30天的太阳同步轨道上布置一颗L波段的合成孔径雷达卫星。 1. 请设计合适的轨道参数，并仿真对应轨道下一个运行周期内星下点轨迹图（纬度和经度两个图）； 2. 计算多普勒中心频率，多普勒调频率与纬度的关系图（设姿态角为0°，天线视角20°~60°，推荐35°）； 3. 按高斯投影方式，将星下点轨迹图投影到地图坐标上。(Now requires a height of 600 ~ 700KM range, return period of 30 days are arranged on a sun-synchronous orbit L-band Synthetic Aperture Radar satellites. 1 Please design the appropriate orbital parameters and simulate the corresponding orbit within the next operating cycle nadir trajectories (latitude and longitude two graphs) 2. Calculate the Doppler center frequency, Doppler frequency and the relationship between latitude Figure (set attitude angle is 0, the antenna angle of 20 to 60, recommended 35) 3 Press Gauss projection, the nadir trajectories projected onto the map coordinates.)
