I have the error “Unexepected Matlab expression”, how can I solve it ?
Hi everyone, I’m trying to build a custom block with the following code :
component pelton_turbine
% Ce composant calcule le couple généré par l’eau sur la turbine.
% 🔹 Déclaration des ports
nodes
H = foundation.hydraulic.hydraulic; % Port hydraulique
R = foundation.mechanical.rotational.rotational; % Port mécanique rotatif
end
% 🔹 Déclaration des paramètres
parameters
eta = {0.85, ‘1’}; % Rendement de la turbine
rho = {1000, ‘kg/m^3’}; % Densité de l’eau
r = {0.5, ‘m’}; % Rayon moyen de la roue
end
% 🔹 Déclaration des variables internes
variables
T = {0, ‘N*m’}; % Couple généré
Q = {0, ‘m^3/s’}; % Débit volumique
H_head = {0, ‘m’}; % Hauteur d’eau équivalente
end
% 🔹 Bloc des équations
equations
Q == H.q; % Débit entrant dans le port hydraulique
H_head == H.p / (rho * 9.81); % Calcul de la hauteur d’eau équivalente
T == eta * rho * Q * H_head * r; % Formule du couple hydraulique
R.tau == T; % Appliquer le couple sur l’axe mécanique
end
endcomponent
I keep having the same error : Unexepected Matlab expression for the last line (‘endcomponent’). I have already checked a lot of sources of error (hidden spaces, checking that the path is good…). Do you have any idea of what might be wrong ?
Thanks in advance,

Implementing MRAC for Robotic arm of unknown link lengths
Hi! I am currently trying to implement MRAC in Simulink for a 3DOF robotic arm, but I’m a bit confused on the block connections and deriving the reference model.
For the reference model im using a 2nd order equation because the system in non linear, but if link length is unknown how do I implement the adaptive control because to use transfer functions the values should be known? The reference model im trying to implement is : b /s^2 +2s + b

Issue with serial communication blocks from support package for arduino nano(CH340 clone)
I’m using arduino nano(ch340) and implementing serial communication with the Raspberry Pi 4B. I’m using USB cable rather than onboard uart pins. I’ve been trying to send data through serial transmit block (from nano) but no results at all. You cannot use ‘monitor and tune’ so only been reading the data(in both Arduino ide’s serial monitor and rasp pi’s terminal) after uploading the model.
The output in serial monitor is gibberish (boxes) while in terminal(screen) it is not visible at all. I generated a model for rasp pi with serial read block from support package where data is zero and status port indicates ‘data not available’. Tried all three modes for transmit block: write, print, println, but same results. I programmed a test program in arduino ide with serial.println function which was successfully displayed results in both terminal and display from rasp pi simulink model. I’ve successfully implemented basic test models like ‘led blink’ in simulink for arduino so my inference is that the problem is only with serial transmit block and its generated code.
My aim is to establish bidirectional serial communication between Raspberry pi and arduino nano, to exchange multiple values simultaneously(probably having different data types) in an array and separate them for their intended use.I’m using arduino nano(ch340) and implementing serial communication with the Raspberry Pi 4B.

I generated a model for rasp pi with serial read block from support package where data is zero and status port indicates ‘data not available’. Tried all three modes for transmit block: write, print, println, but same results. I programmed a test program in arduino ide with serial.println function which was successfully displayed results in both terminal and display from rasp pi simulink model. I’ve successfully implemented basic test models like ‘led blink’ in simulink for arduino so my inference is that the problem is only with serial transmit block and its generated code.
My aim is to establish bidirectional serial communication between Raspberry pi and arduino nano, to exchange multiple values simultaneously(probably having different data types) in an array and separate them for their intended use. serial communication, arduino and raspberry pi MATLAB Answers — New Questions
Ezyfit: Single vs. Two-Step Fitting Problem
Ezfit (actually I am using the updated version from Walter Roberson) fails to accurately determine all 4 parameters in a single curve fit (see Method A). A workaround, setting 1 parameter initially and then fitting the remaining 3 in a second step (Method B), looks instead successful.
Is there a method or setting within Ezfit to obtain accurate 4-parameter results in a single fitting run (Method A)?

Refresh overlaid plots without “hold on/hold off” in each loop iteration
I have a script with multiple figures that are updated in a for loop using their figure and axes handles. One of the figures is a pair of scatterplots overlaid on each other. I need both these concurrent scatterplots cleared at the beginning of each iteration, before updating with the new data for both of them. When using the "hold on" command to overlay the scatterplots on a single figure, I am unable to clear the second one for the next loop iteration using the "set" command. Here’s a snippet of my code:
for i = 1 to N
% Figure 1 (with overlaid scatterplots)
if ~(exist(fig1))
fig1 = figure;
f1 = subplot(2,1,1,’Parent’,fig1);
%% Overlay 2 scatterplots in this subplot %%
sc1 = scatter(x1,y1,’b’,’Parent’,f1);
hold on;
scatter(x2,y2,’r’,’Parent’,f1);
% Other subplots %
else
figure(fig1)
% Update new info for both scatterplots and overlay them in the first subplot
set(sc1,’XData’,x1,’YData’,y1,’CData’,repmat(sc1.CData(1,:)),’Parent’,f1);
hold on;
scatter(x2,y2,’r’,’Parent’,f1);
% Other subplots %
end
% Plot some other figure
if ~(exist(fig2))
fig2 = figure;
ax = axes(‘Parent’,fig1);
% Plot Figure 2
else
figure(fig2)
% Figure 2 plots and legends using ax
end
end
The problem is, the second scatterplot does not get cleared in the next loop iteration when set(sc1,…) is called. I tried the cla(f1,’reset’) command, but that deletes all the XData, YData variables, which I need to exist in order to update.
I think the "hold on" is creating the persistence issue, but adding "hold off" after the second scatter just clears the entire subfigure including axes.

Stability Margins for MIMO Feedback Loop
Hello,
I have this NDI-Controller for the lateral motion of an aircraft modelled in Simuink and want to determine its stabiity margins. I am strugging in how to linearize the open feedback loop. I placed an ‘looptransfer’ analysis point after my Control Allocation, hence the control input. When I now linearize the open-loop with the Model Linearizer, and determine the margins in MATLAB with ‘allmargin(-linsys)’, it says, that my open-loop is not stable.
For me it seems, like I am using the Matlab Linearizer not correctly, as my outputs of the feedback loop seem stable. The same to all the poles.
Does anyone have an idea, how I should linearize the feedback loop to receive the correct gain & phase margins? Would be so helpful.
Thanks a lot.
Cheers,

ThingsSpeak not receiving data from The Things Stack
I have a ERS Co2 sensor. It is connected to the TTN and the TTN is receiving the data. I want to connect it to ThingSpeak.
First, I used the payload uplink formatter recommended by the ELSYS company in the TTN (See the file attached: Elsys_Sensor.txt).
After I went through some ThingSpeak tutorials – I used the payload uplink formatter in the file Elys_Sensor_Adapted with the program returning the required data in Fields.
Still the ThingSpeak doesnt receive any data.
Note: I used the Channel ID and the Write API in the TTN to add ThingSpeak as webhook.I have a ERS Co2 sensor. It is connected to the TTN and the TTN is receiving the data. I want to connect it to ThingSpeak.
