this is assiment for artifical inteleginet

This model provides AC coltage control in MATLAB.

基于稀疏表示的高光谱图像分类的Fisher字典学习方法matlab代码(Hypersynthetic image classification based on sparse representation in Fisher dictionary learning matlab code.)

粒子滤波源代码，适合各种非线性参数估计，和智能算法(Particle filter source code for various nonlinear parameter estimation, and intelligent algorithm)

matlab PID simple s model pid最简单的S模型，可以自己加入扫频信号，就可以看开环伯德图了(matlab PID simple s model)

永磁同步电动机直接转矩控制论文,其中比较了滑模观测器和kalman滤波器的优缺点(SMO-KF compare used in DTC for PMSM drive)

QPSK的锁相环程序，在MATLAB环境下编写的，用来进行QPSK通信系统的仿真和实际信号载波同步的提取(QPSK PLL program, written in the MATLAB environment, QPSK communication system used for simulation and the actual extraction of the signal carrier synchronization)
