    一共有15个m文件,80几个函数,5000多行代码。包含了一般软件的几大块:界面、参数、算法、仿真、演示等。熟悉GUI的朋友感兴趣的问题都有所涉及:比如参数传递,多个界面的操作,m文件构造复杂界面,存取文件,多个axes,读取图片,显示图片(A total of 15 m paper, 80 in several functions, more than 5000 lines of code. Contains several large pieces of software in general: the interface, parameters, algorithms, simulation, presentation and so on. Familiar with the GUI of the Friend of interest issues are involved: for example, transmission parameters, the operation of a number of interface, m file structure is complicated interface, access to documents, multiple axes, to read pictures, show the picture)

    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):

    摘要:经验模态分解方法(EMD )在非平稳信号的分析和处理中起着重要的作用 ,为了能够方便的使用EMD方法对信号进行处理 ,现labVIEW 虚拟仪器开发平台良好的用户图形界面和TLAB 软件强大的数值分析功能相结合 ,利用 Lab V IEW调用 MATLAB实现EMD信号处理方法.仿真结果表明对信号进行EMD分解后,使得瞬时频率具有了物理意义,但只是对信号进行了初步处理 ,可根据实际需要进行相应后续处理 。(Abstract: The empirical mode decomposition (EMD) plays in the analysis and processing of non-stationary signals an important role, in order to facilitate the use of EMD method for signal processing, virtual instrument development platform now labVIEW good graphical user interface and TLAB powerful numerical analysis software combined with the use of Lab V IEW call MATLAB realize EMD signal processing methods. simulation results show that the signal EMD decomposition, so that the instantaneous frequency has a physical sense, but only a preliminary processing of the signal, according to The actual need for appropriate follow-up treatment.)
