MODELING AND SIMULATION FOR VOLTAGE SAGS/SWELLS MITIGATION USING DYNAMIC VOLTAGE RESTORER (DVR)

坐标轮换法求解多维约束问题极值，坐标轮换法求解多维约束问题极值(Coordinate Rotation Method Constrained extremum)

运用一种基于相位信息的2FSK与MSK的调制识别方法,来实现MSK与普通的2FSK的识别。通过计算机仿真表明,在SNRE10dB的条件下,该方法识别率达到了100 。 (Based 2FSK use and MSK modulation recognition phase information to achieve a common 2FSK MSK and identification. Through computer simulations show that, under SNRE10dB conditions, the recognition rate reached 100 .)

“模拟退火”算法是源于对热力学中退火过程的模拟，在某一给定初温下，通过缓慢下降温度参数，使算法能够在多项式时间内给出一个近似最优解。利用模拟退火算法,基于最优下料编码方式,对矩形件进行下料处理。("Simulated annealing" algorithm is derived from the simulation of the annealing process in thermodynamics. At a given initial temperature, the algorithm can give an approximate optimal solution in polynomial time by slowly decreasing the temperature parameter. Based on optimal blanking coding method, simulated annealing algorithm is used to blanking rectangular parts.)

附件程序为图像稀疏表示的源代码，程序用matlab编写，能正常运行。(Sparse representation of the image attachment program source code, programs written with matlab able to function properly.)

采用自相关函数法求基音周期，将采样得到的声音信号按每20ms一帧分为若干帧，并对每帧的序列求自相关函数，取自相关函数第一个最大值点算出基音周期，并以帧为横坐标，基音周期为纵坐标画图，并去除野点，最后取图中浊音部分即面积较大部分的值作为基音周期。(Using the autocorrelation function method pitch period, the sound signal is sampled every 20ms frame is divided into a plurality of frames, and each frame sequence uates the autocorrelation function, taken the first maximum point of correlation function calculated the pitch period, and frame as the horizontal, the vertical axis pitch drawing and remove outliers, and finally take the value of the area that is part of a larger portion of the figure as voiced pitch.)

基于otsu算法的图像分割算法实现，经过多次验证，程序无错误。(Based on Otsu algorithm for image segmentation algorithm, after repeated verification, error-free program.)
