APF基于ip-iq的Simulink仿真模型，学习及分析APF很好的资料，验证可用，文件仅用于学习交流，严禁用于商业用途。(APF ip-iq Simulink models based APF study and analysis of good information, verification is available only for study and exchange files, non-commercial use.)

通过MATLAB中.m语言实现了标准大气模型(The standard atmosphere model is implemented by using matlab )

说明：  系统采用LC滤波，利用PR控制器对逆变器输出电压进行闭环控制。PR控制器在逆变器控制中应用很多。PR控制能够在谐振频率处提供无穷大的增益，因而对谐振频率处的电流信号实现无静差跟踪，并且易于实现，可有效降低系统成本。(The system uses LC filter and PR controller to control the output voltage of inverter. PR controller is widely used in inverter control. PR control can provide infinite gain at the resonant frequency, so the current signal at the resonant frequency can be tracked without static error, which is easy to implement and can effectively reduce the system cost.)

说明：  压缩感知中的正交匹配追踪法重构一维离散信号(Compressed sensing method in the orthogonal matching pursuit signal reconstruction)

说明：  滑模控制算法, matlab仿真，采用m脚本的形式。(The sliding mode control algorithm is simulated by MATLAB in the form of M script.)
