1、在命令行窗口，输入如下命令：load sunspot.datyear = sunspot(:,1);relNums =sunspot(:,2);plot(year,relNums)title('Sunspot Data')。2、按“Enter键”，得到Figure1。2、在命令行窗口，输入如下命令：plot(year(1:50),relNums(1:50),'b.-');。3、信号处理的基本工具是快速傅立叶变...
w = linspace(0,pi/2,30);Wn = 10;x = 5;K = 3;A=K./sqrt((1-(w./Wn).^2).^2 + 4*x.^2.*(w./Wn).^2);G=-atand(2.*x.*(w./Wn)/(1-(w./Wn).^2));figure(1)plot(w,A);figure(2)plot(w,G);这样可以运行。 plot函数中的两个参数必须是维度一致的向量或...
matlab中 错误使用 ^ 输入必须为标量和方阵.要按元素进行 POWER 计算,请改用 POWER (.^). 在线等原程序如下 A(w)=K/sqrt((1-(w/Wn)^2)^2+4*x^2.*(w/Wn)^2);G(w)=-atand(2*x*(w/Wn)/(1-(w/Wn)^2));figure(1)plot(w,A(w));figure(2)plo
如果你只是很简单的想修改由FFT Analysis Tool生成的频谱分析图形,不妨试试下面简单的方法。 在command中新建一个figure >> figure 打开后选择工具下的plot edit 然后右键粘贴即可。 这样你就可以通过set()来设定figure的参数,改变图形的配置。具体要设定gca句柄。 比如 >> set(gca,'yscale','log')%将y轴转换...
Then, the wind–solar power generation model was built in MATLAB/Simulink according to the mathematical model in Section 2.2. The output power of the wind turbines and PV system were calculated in the Simulink model using data on wind speed, temperature, and solar light intensity. Figure 2 ...
Figure 1. The systems under study: (a) IEEE30-bus; and (b) IEEE57-bus. Table 3. Parameters of the IEEE30-bus and IEEE57-bus systems [55]. The second phase of this work has 16 scenarios, and their descriptions are seen in Table 4. These scenarios are classified by test procedur...
Install MATLAB® on the NI PXI controller to run this example with the hardware setup, which is illustrated in the following figure. MATLAB, running on the PXI controller, generates test waveform and downloads the waveform to the VSG. The VSG transmits this test waveform to the PA and the...
Figure5represents the general outline of the control techniques used in this work for AG control, where the Fig.5a show the proposed nonlinear controller in Matlab, Fig.5b show the general form of MRWT in the simulation, Fig.5c shows the proposed DFOC technique of AG-based WT system and ...
The following figure shows a typical conductor arrangement for a three-phase double-circuit line. This line configuration illustrates the various line parameters you specify in theDATAstructure. Configuration of a Three-Phase Double-Circuit Line ...
上面说了,这个工具不过是一个定制版的figure,窗口中也显示出了figure所特有的各种工具,因此,你可以按照figure的修饰方法“再加工显示出來的图形。4.5小结到此,我们介绍了powergui分析工具中的比较简单并常用的三个。FFT和LTI也很常用并且很有用,不过涉及到比较多的内容,还是留在后而专题讨论吧!
