Relationship between back EMF (Ke) and maximum achievable speed
Is there a standard relationship between DC bus voltage and the maximum achivable speed, from which we can calculate the maximum achvable speed of a PMSM motor given the DC bus voltage?
Looking at this thread:
https://e2e.ti.com/support/motor-drivers-group/motor-drivers/f/motor-drivers-forum/1271711/mcf8315a-speed-control-issue
Is the formula given there a valid equation for a general FOC controller?
Eletrical frequency = (DC bus / sqrt(3))/Ke ?
We are trying to run the Motor driver from a C2000 LaunchPad (LAUNCHXL-F28379D + BOOSTXL-3PHGANINV)

how to save my 3d matrix in X,Y,Z coordinates
I have 134* 2d matrix (86*86 each) and they make 86*86*134 matrix.

how can I save the matrix (I) in xyz table
my matrix (I) was generated by the following code
clear all

names=dir(‘inter the name of your file*.tiff’);

Diode fitting with 5 parameters
I used fsolve function (advised by Mischa Kim) to solve the diode equation and it worked (with small modification on (q/nkT).
fun = @(I) Il – Io * exp((V + I*R)/(n*kT_q)) – (V + I*R)/S – I;
Now I need to do a fitting using the same equation but this time I need Matlab to iterate the values for:
Il , Io, R, n, S,
in order to solve I which will give me the best fit against the experimental I (Iexp) where V is the independent variable. I guess I will need the least square function for that but first how do I ask Matlab to do the iteration and eventually solve the I?
Thank you very much for your help.

Error: output is inferred as a variable-size matrix, but its size is specified as inherited or fixed.
To simplify the question, when I define the size of my output based on a constant input (it won’t change during the simulation), i receive the following error: ‘y’ is inferred as a variable-size matrix, but its size is specified as inherited or fixed. Verify ‘y’ is defined in terms of non-tunable parameters, or select the ‘Variable Size’ check box and specify the upper bounds in the Size box.
Other people had this problem but I couldn’t really find a way to fix it. I can’t select the variable size check box because it lead to other errors. I also don’t have the coder library. I got that in theory this constant value can me modified and then cause problems, but it isn’t my case, I just want to define it when the simulation starts.

Curve fitting 3d closed surface

Is there an easy way to do this with Matlab or any toolbox? I’ve seen curve fitting toolbox but it doesn’t look like it would fit a closed 3d surface since the curve fitting looks polynomial based.

uigetfile() goes behind main figure
Hi,
uigetfile(), I think, creates a new figure; it has no parent argument. A number of people complained that its dialog window has unexpeced bahaviour in terms of appearance and focus.
I’m calling it from my main figure (created programmatically with uifigure). The uigetfile() dialog opens as a child of MATLAB window, and NOT as a child of my GUI app which is actually calling it. I.e. it opens behind the main app (problem #1); you need to click on Matlab icon to see this dialog, then, once you select file(s) the focus remains with Matlab window, then, to come back to your app (problem #2), again, manually click on your app to give it the focus.
I found one workaround which seems failing in 2021b on Mac–the dialog still opens behind the main calling app:
f2 = figure(‘Visible’,’off’); % create a dummy figure
drawnow; % give it a focus
[file, path] = uigetfile(…); % call this stubborn thing
delete(f2); % delete dummy
% the above does not work on Mac
% then the 2nd workaround, to give focus back to the calling main fig
% it works fine
drawnow;
figure(f); % f is a handle of the main fig, created with uifigure()
Anybody can help to open this dialog on top of the main app?
I’m on MacOS Monterey. It could be OS dependant, I’m afraid.
The thing is: the new figure is spawned inside uigetfile(), and currently uigetfile() has no way to explicitly mention the parent, therefore, I believe it is Java/OS who decides on the ancestor. And at least on Mac it decides to open it in the main Matlab window. Maybe the dummy figure workaround works on Win (or there is no problem #1 on Win in the first place). One can work with Java window manager to change the focus, but this needs to be done right after the appearance of the dialog, i.e. inside the uigetfile(), not before or after its call.
Eventually, I want to compile the app to a standalone. Thus, there will be no Matlab main window. Maybe then it will behave better. What I’m hearing from others is that this appearance/focus behavior is not consitent between App-Design-created vs programmatical, compiled vs in-Matlab, and diff versions.

About the solution type in OOPs OnRamp course in Matlab
There is one particular course in Matlab called OOPs OnRamp which is really hard to solve even with the help of the solutions nearby. I feel that it is because of the file format. In that course, we are to type our solutions in different files and run them seperately and finally solve them which is really difficult for me and many of my friends. Is there any explanation for the course to solve? All the lessons in that course is hard to do.There is one particular course in Matlab called OOPs OnRamp which is really hard to solve even with the help of the solutions nearby.

Error encountered in the Deep Signal Anomaly detector while running the official SIMULINK example
Hi all,
I am runnining this official Simulink example here: fault_localization in 3-phase power line.
I had a somewhat different circuit and thus I trained a new model following this guideline. However, after training my deep anamoly detector and while trying to apply this trained model to my detection model, I keep getting this error as shown in this screenshot:
Any suggestions on how to fix this? I’m pretty sure I used the
saveModel
command to save the parameters of my trained model. It looks like the model parameters file in the provided example works here, but mine wouldn’t work. I spent quite some time on this but still haven’t figured out a solution.Hi all,

Unexpected behavior resulting from the Three-Phase-Fault block in my simulated circuit (Simulink)
Hi all,
I am simulating a circuit with a 3-phase fault inserted as shown here:
My goal is to simulate the fault at different locations by varying the length of the Distributed Parameters Line blocks many many times, and then collect the 3-phase voltage + current data for training a deep neural network for fault localization. Thus, I used an external control signal to somewhat randomly switch on and off the three-phase-fault block as shown here:
Where SysModel is the one I just showed earlier.
However, the weird thing happens. The external control signal to the 3-phase-fault occurs at around 0.01 second (determined by the pulse generator and delay), and lasts for 0.01 seconds. But the resulting 3-phase voltage and currents in the Time Scope look like this:
this does not make sense because:
There is no transient resposne in the currents at all
The transient response in the voltages should die out shortly after 0.02, but somehow it automatically turns up again toward the end of the simulation.
Here is the time scope for the external control signal that’s going into the 3-phase-fault block (From "Composite Signal 1" in the previous screenshot):
In addition, I am using the following settings for the Distributed Parameters Line blocks:
