断裂参数计算

用amra实现的风电功率预测，代码可直接运行(Wind power forecasting realized by amra, the code can run directly)

说明：  采用simulink搭建IEEE标准33节点仿真模型及.m程序(IEEE standard 33 node simulation model)

蠕滑力计算,滚珠轴承中蠕滑力计算时用到，修改后也可以用到滚珠丝杠中(fastsim function F=Get_Fastsim(C,Cp,ab,N))

说明：  直流配网模型，非常基础的直流配网模型，便于对直流配网的基本掌握和学习(DC distribution network model, very basic DC distribution network model, easy to grasp and learn the basic DC distribution network)

用晶闸管建立的12脉动特高压直流输电模型(12 pulse HVDC model based on thyristor)

说明：  单相全桥双极性逆变器，可以用来学习、仿真双极性控制(single phase full bridge inverter, bipolar)

说明：  对于非线性模型的跟踪预估问题，摒弃额对非线性函数进行线性化的做法，采用无迹变换处理均值和方差的非线性传递问题。(For the tracking and prediction problem of the nonlinear model, the linearization of the non-linear function is abandoned, and the traceless transformation is used to deal with the non-linear transfer of mean and variance.)
