三相PLL锁相环的闭环系统仿真模型，仿真并分析三相输入信号包含谐波、不平衡、负序和直流偏移时锁相环的锁相结果(Closed-loop system simulation model of three-phase PLL phase-locked loop,Simulation and analysis of phase-locked loop results when three-phase input signals include harmonics, unbalance, negative sequence and DC offset)

gps与matlab仿真，模拟卫星的运动,后续程序正在写。(gps with matlab simulation, motion simulation of the satellite, the follow-up program is being written.)

数据挖掘聚类算法中，K-means的matlab实现(Data mining clustering algorithm, K-means the matlab implementation)

3 phase Active Power filter that is simulated in matlab simulink based on hysteresis current control method

视频运动估计中快速块匹配方法 十字菱形搜索(The video motion estimation based on fast block matching Cross Diamond Search)

This is approximate entropy and sample entropy article. It will be helpful for motor behavior and rehabilitation study.

说明：  信号检测与估计理论的一本好书，这方面的原版书籍不是很多，这是比较清晰而且可以借鉴的一本(Signal detection and estimation theory of a good book, this is not a lot of original books, it is more clear and can draw on a)

二阶粒子群，比pso更加精确更加灵敏地优化函数。在标准pso算法中，微粒的飞行速度仅仅是微粒当前位置的函数，而二阶粒子群算法中微粒飞行速度的变化与微粒位置的变化有关(Second swarm, more sensitive and more accurate than pso optimize function. Pso algorithm in the standard, the particle particle flight speed is only a function of the current position, the second particle swarm flying speed of particles in the particle changes related to changes in the position)
