BP神经外那个罗可以逼近任意函数，此为拟合函数的源代码(BP neural network can approximate any function, the source code for the fitting function)

建立了基于matlab语言的四位全加器仿真模型，通过了系统验证。(Matlab language is established based on four full adder simulation model, verified by the system.)

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.)
