该程序实现的锁相环，运行环境为matlab，二阶的环路滤波器(The program realization of phase-locked loop, operating environment for matlab, the second-order loop filter)

说明：  实现KALMAN滤波算法，通过跟踪，估计物体运动轨迹。(achieve Kalman filtering algorithm, by tracking estimated object trajectories.)

code about face reading. it reads the face

Direct Torque Control, Induction Motor Vector Control Without an Encoder dtcc

本程序主要是系统辨识滤波中，卡尔曼滤波与改进卡尔曼滤波程序，该程序可以用于目标定位追踪中，预测目标的下一个状态。(This program is a system identification filter, Kalman filtering and Kalman filtering procedures, the program can be used for targeting tracking, predict the target state.)

KALMAN filter for linear time invariant estimation

求矩阵的逆阵，利用高斯消去法，是本人编写的MATLAB源码(Inverse matrix array, the use of Gaussian elimination is, I prepared MATLAB source)

轴承故障谱峭度分析，打开直接运行，包含包络谱分析(Bearing failure analysis of spectral kurtosis, open directly run, including envelope spectrum analysis)

简易模拟时钟，使用MATLAB的GUI开发而成，可以获取桌面时钟数然后在模拟钟面上显示，每隔一秒刷新显示！(Simple analog clock, a GUI was developed using MATLAB, you can get a desktop clocks and analog clock face on display, refresh the display every second!)

基于MATLAB的matrix_gain详解，主要解决的是matrix_gain的问题(Based on MATLAB-matrix_gain explain, the main problem lies in the question of matrix_gain)
