Hi,

I am trying to design a Simulink model for transmission cable to characterize some features of an existing electrical system. I am using the Lumped Parameter L-section with few segments. I want to set initial conditions to each segment capacitors. Is there a way I can set those?

Thanks in Advance.

Actually i have chosen the DC link capacitance in my inverter circuit. i wanted to know how to perform a simulation of it in MATLAB and to check the affecting parameters when the capacitance is varied and obtain a 3D graph.

I have simulated the photovoltaic (PV) module on Simulink as in my simulation. I want to transfer the signals of I-V scope into the plot in Matlab. But the scope do not show the voltage value on the X-axis. Instead, the X-axis shows the time. As a result, when I use the data saved in Matlab workspace, I just get the current-time plot instead of current-voltage plot. How can I fix this problem ? ( The current-time plot is the same as the I-V characteristic in datasheet of the PV panel, but the X-axis expresses the time value. I want to change it into voltage value)

Hello Everyone,

I would like to perform the cross correlation function (crosscorr (y1,y2)) for my data but donot have the Econometrics Toolbox to compute this. Can someone in here help me to get this toolbox or else show me where I could get one?

many thanks, Tobias

After reading Rik's comment I looked for a list of Matlab releases and their corresponding features. Wiki: Matlab contains an exhaustive list, but what about having a lean version directly in the forum?
If this is useful, feel free to expand the list and to insert additions. Thank you.

Hi. I'm new to matlab. I'm a hobbyst, not a company or anything like this. I brought MATLAB personal with some modules and I'll use to learn FPGA with ZedBoard + AD9361. I know that this board (both) are supported by simulink and I'll test/learn using simulink and block-design. My plan is to make an FM transmitter (for start) when my boards arrive (already brought, still waiting delivery). After that, my plan is to make an receiver and then, do the same receiver, but using another frontend (including ADC). So my question is: imagine that I have plugged in another ADC into my ZedBoard (let's say AD9226), is possible to read this ADC in simulink, like AD9361 does? If yes, how? Where can I find any article or tutorial about this?

Even further: if I want to generate HDL code in the future (using HDL Coder), how can I integrate this 'custom' AD for code generation?

PS: I know that I can't buy HDL Coder for personal. My plan is to use trial for testing, since I'm using just for learning.

Thank you.

I am trying to design the outer voltage loop of the inverter but i am unable to remove the 5,7th harmonics from the capacitor voltage as i am trying to supply nonlinear load. The file is in matlab2018b.

Model-Based Design speeds up developing embedded software for controllers in power electronics-based systems. Wherever you plan to use digital controls, you can use Model-Based Design to develop, test, and implement your algorithms. You can learn more about Model-Based Design in this white paper .

1.When I am trying to code my TMS320F28379D for running a three phase grid tied plant as per the attached image a scope in "SYNCHRONOUS SYSTEM " is showing perfect result but the result is not getting transferred to the "PI_Controller_ISR ".I have concluded this after I have connected the scope at the signal which is entering the "PI_Controller_ISR " subsystem (Inside the subsystem). I am trying to do this in MATLAB 2018B AND F28379D LAUNCHPAD.I am attaching the MATLAB fILE with this help request.Kindly resolve the issue. 2. I have been working on how to send the ADC signal from the C2000 MCU to the Host by seeing the video of** f28379D_DCDC_Buck** in external Mode, but when I downloaded the file and tried to run it by setting the parameters in the HARDWARE IMPLEMETATION pane it is showing me the error message. " Error evaluating 'InitFcn' callback of C28x SCI Receive block (mask) 'c28379Dpmsmfocdual_cpu1_ert/Serial Receive/SCI Receive'.

Hi, How to represent a transfer function (TF) of a compensated system in MATLAB to plot the bode plot of it, without expanding the denominator? The TF is: T(s) = (1 + s/Wz) / ( (1 + s/Wp) * ( 1 + s/Wo + s^2/W0^2 ) )

There are multiple ways to create a graphical user interface (GUI) in Matlab. Which method is the best depends on multiple factors: the complexity of the project, to what extent it should be a long-term solution, on what releases your GUI should work, your available time, your skill level, and probably other factors I'm forgetting.
To keep the thread clear I'll attempt to provide a short outline a few ways in this question, and leave the details for the answers. (@anyone with editing privileges: feel free to update the section below if I missed something important and am slow in editing this question)
---------------------------------------------------------------------------------------------------
GUIDE
GUIDE is probably the first tool new users will encounter. It is very useful for quickly putting something together, but it is otherwise fairly limited. It requires maintaining (and distributing) both a .m and a .fig file. Note that the GUIDE environment will be removed in a future release. After GUIDE is removed, existing GUIDE apps will continue to run in Matlab but they will not be editable in GUIDE. If you're starting a new GUI, don't use GUIDE. If you're updating an existing GUIDE GUI, migrate it to AppDesigner. In R2021a the first step for this removal was taken: all templates except the blank template have been removed.
GUILT
Although I haven't had a detailed look myself, it seems a list like this is not complete without at least mentioning the GUI Layout Toolbox, which is available on the file exchange and offers a lot of customization options.
Programmatic GUIs
You can bypass GUIDE and use the normal figures and functions like uicontrol to build GUIs from code. This makes the design less visual, but more flexible for future additions.
App Designer
The official successor to GUIDE, AppDesigner is not based on functions, but works similar to a class. It uses uifigure and mostly uses graphical elements that are incompatible with 'normal' GUIs that are created with a figure (or .fig).
