97年中国大学生数学建模竞赛B题（枚举法） (1997 China Undergraduate Mathematical Contest in Modeling B (enumeration))

自己在simulink里搭建的感应电机空间矢量控制(SVPWM)系统，结构清楚，便于移植，已经在Matlab R2013a上测试过，希望给大家带来帮助(It is a SVPWM induction motor control system built in simulink, the structure is clear and it is easy to transplant.Tested in Matlab R2013a. May it be helpful.)

信号与信息处理-matlab信号处理工具箱源程序集合(signal processing toolbox matlab source code collection)

说明：  标准粒子群算法的matlab源程序 可以直接运行(Standard particle swarm algorithm matlab source code can be run directly)

本程序是一个用LSSVM实现简单煤炭数据先拟合程序，用MATLAB编写。(This procedure is a simple to use LSSVM first coal data fitting procedures, prepared by MATLAB.)

经验模式分解程序（简称EMD），在某些情况下比WAVELET TRANSFORM 和STFT分析效果要好，就是计算很费时间！(Empirical Mode Decomposition (EMD), In some cases than WAVELET TRANSFORM STFT analysis and better results. Computing is a great time!)

说明：  用MATLAB实现了多相滤波器的仿真(Using MATLAB realize the polyphase filter simulation)

The model used for creating the reference voltage is shown in Fig. 4. First, photovoltaic output current (Ipv) and output voltage (Vpv) are passed through a first order low pass filter with a magnitude of G = 1 and a time constant of T = 0.01 seconds in order to filter out the high frequency components or harmonics from these signals as shown in Fig. 5 and Fig. 6. The filtered current and voltage signals (Ipv_F and Vpv_F) are then fed into the MPPT control block that uses the Incremental Conductance Tracking Algorithm. An algorithm that is based on the fact the slope of the PV array power curve shown in Fig. 7 is zero at the Maximum Power Point (MPP), positive on the left of the MPP, and negative on the right. The MPP can thus be tracked by comparing the instantaneous conductance (I/V) to the incremental conductance (∆ I/∆ V) [11] as in (1):
