优秀论文及配套源码。首先阐述了负荷预测的应用研究现状，概括了负荷预测的特点及其影响因素，归纳了短期负荷预测的常用方法，并分析了各种方法的优劣；接着介绍了作为支持向量机（SVM）理论基础的统计学习理论和SVM的原理，推导了SVM回归模型；本文采用最小二乘支持向量机（LSSVM）模型，根据浙江台州某地区的历史负荷数据和气象数据，分析影响预测的各种因素，总结了负荷变化的规律性，对历史负荷数据中的“异常数据”进行修正，对负荷预测中要考虑的相关因素进行了归一化处理。LSSVM中的两个参数对模型有很大影响，而目前依然是基于经验的办法解决。对此，本文采用粒子群优化算法对模型参数进行寻优，以测试集误差作为判决依据，实现模型参数的优化选择，使得预测精度有所提高。实际算例表明，本文的预测方法收敛性好、有较高的预测精度和较快的训练速度。(first expounds the recent application research of load forecasting, summarized the characteristics of load forecasting and influencing factors, summed up common methods of short-term load forecasting, and analyzed the advantages and disadvantages of each method then introduced statistical learning theory and the principle of SVM as the basis of support vector machine (SVM ) theory, SVM regression model is derived this paper adopted least squares support vector machine (LSSVM) model, according to the historical load data and meteorological data of a certain area of Zhejiang Taizhou, Analysised the various factors affecting the forecast, summed up the regularity of load change , amended "outliers" in the historical load data,the load forecasting factors to be considered were normalized. The two parameters of LSSVM have a significant impact on the model, but it is still soluted based on the experience currently. So, this paper adopted particle swarm optimization algorithm to optimized )

该模型实在simulink下建立的质子交换膜燃料电池模糊控制模型，可以借鉴或者直接使用(fuel cell)

该程序（基于matlab）为小波变换在数据压缩方面的应用。原理：数据可分为高频部分和低频部分，高频部分反映了细节，而低频部分则反映概貌，故压缩部分应为高频部分。数据经此程序变换后将压缩为原来的一半。(This program (based on matlab) for the wavelet transform applications in data compression. Principle: Data can be divided into high-frequency part and low frequency, high frequency part of the reflection of the details, partly reflecting the profile of low frequency, it should be for the high frequency part of the compression part. Data will be compressed by this program change to the original half.)

读取Yokogawa DL 750, DL 1600 系列 与 DL 7440 示波器的数据. 特点：允许多个通道（trace）的输入，如： [x(:,1:4),x(:,5)]=wvfreadb_moreinput(filename, 1, [1,2,3,4], 1) (loads YT-waveform data from*.wvf file saved by Yokogawa DL 750, DL 1600 series and DL 7440 Oscilloscopes into the variables y (y data) and t (time data). The matrices ind_over and ind_under, illegal contain the indices of overranged data points outside the upper/lower limit of the TDS AD converter and indices of illegal values. advantage：permit several traces, e.g. [x(:,1:4),x(:,5)]=wvfreadb_moreinput(filename, 1, [1,2,3,4], 1) )
