App designer places code (grayed out) that shows an error. I will note that the code ran fine before I saved and closed it out and then later restarted the app. I think the issue might be related to the fact that I had a callback that used the delete function which is used to close the app.

The line that show the syntax error is the following and bold in the full code listing:
app.RawdataPlotterAppUIFigure.CloseRequestFcn = createCallbackFcn(app, @delete(gcf), true);

endApp designer places code (grayed out) that shows an error. I will note that the code ran fine before I saved and closed it out and then later restarted the app. I think the issue might be related to the fact that I had a callback that used the delete function which is used to close the app.

The line that show the syntax error is the following and bold in the full code listing:
app.RawdataPlotterAppUIFigure.CloseRequestFcn = createCallbackFcn(app, @delete(gcf), true);

end App designer places code (grayed out) that shows an error. I will note that the code ran fine before I saved and closed it out and then later restarted the app. I think the issue might be related to the fact that I had a callback that used the delete function which is used to close the app.

The line that show the syntax error is the following and bold in the full code listing:
app.RawdataPlotterAppUIFigure.CloseRequestFcn = createCallbackFcn(app, @delete(gcf), true);

Hello,
I have a problem which should be simple but I can’t figure out the best solution.
I have a real signal, cos of frequency f + noise of N points :
signal = sqrt(2 * Ps) * cos(2 * pi * f *t);
noise = sqrt(Pn) * randn(1, N);
total = signal + noise;
I consider the SNR on the whole signal Ps/Pn that I also check using
(mean(abs(signal.^2)) – mean(abs(noise.^2))) / mean(abs(noise.^2))
I filter this signal using a simple FFT of nFFT points and consider an extraction in the signal canal. For instance, with f / fs = 1/4, I consider the nFFT / 4 + 1 canal. Plotting the signal spectrum, I ensure the signal is centered in the FFT canal. Then I compute :
The power in the canal : PsCanal = mean(abs(samplesCanalWithSignal.^2)).
The noise level in a random other canal : PnCanal = mean(abs(samplesCanalWithoutSignal.^2))
And compute SNR in the canal : SNRCanal = (PsCanal – PnCanal) / PnCanal.

Now I consider a complex signal. Same time, fe, etc… I only change signal and noise definition in order to have same global powers :
signal = sqrt(Ps) * exp(2i * pi * f *t)
noise = sqrt(Pn / 2) *(randn(1, N) + 1i * randn(1, N))
total = signal + noise
When I compute the global RSB, I have the exact same RSB than with real signal.
Then I compute the FFT (same nFFT points) and compute SNRCanal = (PsCanal – PnCanal) / PnCanal

Result is the following (compared to real signal test) :
Same PnCanal
PsCanal multiplied by 2
RSBCanal multiplied by 2
Where am I wrong ? I would like to be able to estimate the correct SNR in the FFT canal for real signals… I understand the PSD of the cos is half the one of exp due to positive and negative frequencies, but don’t understand why it is not the case for the noise PSD. Do I have to transform something ?

Thank youHello,

Hi.

I am trying to estiamte a Hammerstein Model. I have a state representation of the linear block to generate the Hammerstein model, however for some reason the idnlhw function convert the state representation that I have to polynomial form. The above should not be a problem, but the poles of linear block are close together due to the slow dynamcis of my system. From what i read in this post https://la.mathworks.com/help/control/ug/sensitivity-of-multiple-roots.html closelied space poles are very sensitivy to model transformaiton from state space to polynomial represntation.
The above becomes problematic because I want to program this model in a 32-bit microncontroller but this pole sensitivy changes the value of my poles when I convert them to single precision.

How can I solve this issue.Hi.

I’ve been having trouble getting the DC Motor block’s results for current and rotational velocity to match what I obtain when using coupled differential equations in an ODE45 script. The results are very far apart and I’m not sure what is causing this.
The systems of equations I’ve implemented in ODE45 is standard in the DC motor literature, and is as follows:

Where is the current (), is the armature inductance (), is the armature resistance (), is the motor electrical constant (), is the voltage of the constant voltage source (), is the armature’s mass moment of inertia (), is the motor’s torque constant (), and is the motor damping ().

However, I’ve noticed that in the DC Motor block documentation, the equation for torque across the motor is given as (where is the damping constant). When I add the first term into my differential equation model, the results of ODE45 and Simscape Electrical become very close. I assume that this is the set of equations that Simscape is using, but I don’t like to use equations without understanding them. Where does this added term come from? I don’t believe I’ve seen it in the literature.

I’ve attached plots showing current and rotational velocity of the motor for the three models, so that you can see the discrepancies. (Note that there is zero damping in any of the models, yet only the classical differential equation model shows a rising angular velocity — the other models eventually reach some steady-state non-zero angular velocity.)

Any insight into what is happening here would be appreciated.I’ve been having trouble getting the DC Motor block’s results for current and rotational velocity to match what I obtain when using coupled differential equations in an ODE45 script.
