Hi Mladen,
I understand that you want to write MATLAB code to sample a sine wave signal generated in a Simulink model.
I assume you have a Simulink model with a sine wave block and you want to capture or sample this signal using MATLAB.
In order to sample a sine wave signal from Simulink using MATLAB, you can follow the below steps:
Create a Simulink Model:
Open Simulink and create a new model with a “Sine Wave” block and a “To Workspace” block to output the signal.
open_system('new_model'); % Open a new Simulink model
Configure the Sine Wave Block:
Set the parameters of the “Sine Wave” block such as amplitude, frequency, and sample time according to your requirements.
set_param('new_model/Sine Wave', 'Amplitude', '1', 'Frequency', '1', 'SampleTime', '0.01');
Connect the Blocks:
Connect the “Sine Wave” block to the “To Workspace” block to store the signal in the MATLAB workspace.
add_line('new_model', 'Sine Wave/1', 'To Workspace/1');
set_param('new_model/To Workspace', 'VariableName', 'sineData');
Simulate the Model:
Run the simulation for a specified duration to capture the sine wave data.
sim('new_model', 'StopTime', '10'); % Simulate for 10 seconds
Analyze the Sampled Data:
Access and plot the sampled sine wave data stored in the workspace.
plot(sineData.time, sineData.signals.values);
xlabel('Time (s)');
ylabel('Amplitude');
title('Sampled Sine Wave');
Refer to the documentation of “sim” function to know more about its usage:
Hope this helps!
