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)

hi MPPT on the designed bosst circuit does not work correctly. can you help?

From where i can start to learn . Please suggest a particular topic or lectures.

Hi,Everyone,I am new member here. I want to learn simulation on projects. Please suggest, from where i can start Simulink easily and learn from Basics to Advance level.

have anyone use multiobjective function optimization via PSO namely MOPSO ?? I need some help

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

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.

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'. Callback string is 'c28xsci_callback('renderDisplay') validateC280xSCI('Rx'); codertarget.registry.registerC280xSCIRxBlocks(gcb);

                                                   '
Caused by:
The SCI module A is already used by another block or by External Mode."
Kindly resolve these issues.

Please send me some plant digital twin simulink model for productive maintenance.

i want to model LI+ battery , i referred to matlab model https://www.mathworks.com/matlabcentral/mlc-downloads/downloads/submissions/36019/versions/29/download/zip but not able to understand how to make simscape battery parametrs(like R C ), anybody can help ??

Determining State of Charge

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 ) )

I am simulating the attached paper on modulated model predictive control. I have done everything as in the paper. Can some please tell me about my mistake? I am so frustrating since two weeks. Thanks&Regards, G.Sivakumar.
