三项锁相环：利用park变换和clark变换，将三相电网电压，变换为两相旋转坐标系下的电压。同时跟踪A相电压的相位角(Three phase-locked loop: the use of park conversion and clark transformation, the three-phase voltage, transformed into two-phase rotating coordinate system voltage. While tracking the phase angle of phase A voltage)

its a simulation of a fight with the mythical greek hydra.

本次实验是无线楼宇数据传输仿真，即在楼内实现点对点的无线数据通信，需要获得的关键是两点之间的距离和楼层衰减。通过了解914M的楼宇通信特性，建立楼宇数据通信系统的仿真模型，采用无线收发芯片NRF905,实现楼宇内的数据通信仿真分析。 (this experiment is building wireless data transmission simulation, in the building of peer-to-peer wireless data communications, need, the key is the distance between two points and the floor attenuation. 914 M by understanding the communication characteristics of the buildings, the establishment of building data communications system simulation models, adoption of wireless transceiver chip NRF905 achieve buildings on the simulation analysis of data communications.)

This program includes the Simpson s equation for tridiagonalmethod implementation in matlab.

多层次合作型协同演化算法，自适应分组规模的方法首次在CC中被应用(Multi-level cooperative co-evolutionary algorithms, adaptive packet size approach was first applied in the CC)

利用自然梯度算法来对于5 类信号进行盲信号分离，采用自然梯度法对混合的信号进行 分离并分析其性能，并比较不同步长对于信号分离的影响(Use of the natural gradient algorithm for the five types of signals blind signal separation, using the natural gradient method for mixed signal Separation and analysis of its performance and compare sync signal separation for the impact of long)

本文利用编写的MATLAB软件结合解析法证，分析了一种新型的接地距离继电器在系统振荡时再发生单相经过渡电阻接地短路时的动作特性。该接地距离继电器的动作判据是通过比较故障后测得的母线电压、补偿电压、零序电流和负序电流四个量的相位关系以确定继电器的动作行为情况 (In this paper, written in MATLAB software analysis and forensic analysis of a new type of ground distance relays in the system oscillation movement characteristics of single-phase transition resistance is shorted to ground. The operating criteria for the ground distance relay bus voltage is measured by comparing the failure, the phase relationship of offset voltage, zero sequence current and negative sequence current four amount to determine the relay actuation behavior )
