I don't know how to use SIMULINK... Also, the science of control systems is my Minor field of research ... I want to enhance my skills for this field.. Help me to plot and estimate the characteristics of this integral pressure controller (see the attached block diagram) due to a step pressure signal (p1=220000) and a step disturbing temperature signal (T2=50). Take: (c=2.7) and (R=287) ... Kindly, attach MATLAB m file if possible
in the model library, there is a group of blocks called Sinks, choose the scope, drag it and drop it in the model.
connect the scope to whatever signal you want to view.
I just did it because I was curious about the result. you can do it by yourself in Simulink.
Selim Sivrioglu Thank you ... It will be a good start ... can you show me the steps as snapshots on pdf file?
Selim Sivrioglu Thank you very much ... you are very kind ...
Dear Sir
I attach the simulink of your picture
You can change the simulink value
Because I expect there is a lack of information
Abbas Miry Thank you. It worked.. Is it possible for the gain to depend on the output signal? I mean ... c=f(p2) ... for example c=5*p2+4
Abbas Miry Thank you very much for spending time to help every one who see this... Is it possible to take .m file from SIMULINK app ... I mean, can you take out the MATLAB code that when you execute it will give you the same results of SIMULINK app... The reason behind my question is that : Can I make a simulation to change the Gain or other parameter like the value of disturbance signal from 10 to 100 step 10??
Abbas Miry After saving both files into the same working directory, then hit the Run icon of m1 file. It gives the following error:
Undefined function or variable 'k'.
Error in m1 (line 9)
k=k+1;
Note:
I use MATLAB version 2017b
When I double click the prs file ... It gives me error 145 and says you use MATLAB version 2018b ... I think you should save it as older version.
Thank you.
Abbas Miry After deleting the line : k=k+1; and run the file m1. It give me this error:
Error using m1 (line 10)
Model 'prs' was created with a newer version (R2018b) of Simulink
To disable this error message, use Simulink preferences.
To create a model that is compatible with this version of Simulink, load the model
in Simulink R2018b and select File > Export Model to > Previous Version.
Abbas Miry Thank you again ... One missing thing ... Its the Legend on the graph. Can you add 3 or 4 legends??
