Robtic System

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)

说明：  MATLAB OFDM仿真代码，采用QPSK调制(MATLAB OFDM simulation code, using QPSK modulation)

在abaqus中可以实现零厚度的cohesive插入(Implementing cohesive insertion with zero thickness)

说明：  针对带储能的光伏系统出力不稳定问题，基于储能变流器提出了一种带有灰色补偿的Back-stepping控制方法，以实现对并网点上层规划层面有功功率P和无功功率Q指令的跟踪控制，同时保证并网点电压的 稳定。(Aiming at the problem of output instability of photovoltaic system with energy storage, a back stepping control method with gray compensation is proposed based on energy storage converter to realize the tracking control of active power P and reactive power Q command at the upper planning level of the parallel network, and to ensure the stability of the voltage of the parallel network.)

实测可用的PV特性分析，增加几个个人搜集的扰动观察法代码，可以共同学习研究(The available PV characteristic analysis of the actual measurement can be added with the disturbance observation code collected by several individuals, which can be studied together)

说明：  lm求解非线性方程组(Solving nonlinear equations by LM)

说明：  ABAQUS二次开发—材料初始失效准则及损伤演化准则(criteria for initial failure and damage evolution of materials)

频率分集阵列发射波束图仿真，发射波束具有距离-角度耦合性，发射波束图最大值周期性出现，周期等于c/Deltaf。另外，提供了仿真所用的参考文献。(Transmit beamforming of frequency diverse array is range-angle dependent and its maximam is periodic occurrence. the period is equal to c/Deltaf. besides, the references are provided.)

用abaqus做的金属切削仿真，希望可以帮助大家(A metal cutting simulation, i hope it will be helpful)

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.)
