matlab LPC 基于线性预测的参数编码(matlab LPC Parameter coding based on linear prediction)

灰色预测是通过鉴别系统因素之间发展趋势的相异程度，即进行关联分析，并对原始数据进行生成处理来寻找系统变动的规律。(The grey prediction is to identify the different degree of the development trend between the factors of the system, that is, to carry on the correlation analysis, and to process the original data to find the law of the system change.)

说明：  tarjan算法求解有向图中的简单环，非常好用(Tarjan algorithm is very useful for solving simple rings in directed graphs.)

通过设置不同的参数，生成BA无标度网络。(This progarm is to create a BA network by setting different parameters.)

统一潮流控制UPFC仿真模型，230kV(Unified power flow control UPFC simulation model, 230kV)

说明：  主要用于ansys workbench提取结构件的刚度矩阵，希望能帮助到有需要的人(It is mainly used in ANSYS Workbench to extract the stiffness matrix of structural parts, hoping to help people in need)

说明：  关于J2塑性流动理论的金属3的材料本构隐式子程序umat(Implicit Subprogram UMAT for Material Constitutive of Metal 3 in J2 Plastic Flow Theory)

abaqus 使用技巧-Inp文件中单元类型改变时，一定要注意，划分网格的时候是否，选用了一种望各类型，比如4变形和3变形的区别，如果用注意将所有的单元类型都做相应的修改。这说明单元类型由2个因素决定，1网格形状，2计算任务.(Abaqus tips-When changing the unit type in the Inp file, be sure to pay attention to whether or not to select a type, such as 4 deformation and 3 deformation, if you use the attention, all the unit types should be modified accordingly. This shows that the unit type is determined by two factors, 1 grid shape, 2 calculation tasks.)

七自由度冗余机械臂的阻抗控制，并实现自动对奇异构型的避免，通过设置性能指标，自动对机械臂此时性能指标的变化进行判断并修正机械臂轨迹(The impedance control of the seven degree of freedom redundant manipulator is realized, and the automatic configuration is avoided. By setting the performance index, the change of the performance index of the robot arm is automatically judged and the trajectory of the manipulator is corrected)
