No block called 'AirFrame' could be found

'Airframe' is a Subsystem in my Simulink model. Using set_param to change a parameter (Gain) value inside 'Airframe' it suceeds. But when trying to do the same for a Subsystem inside 'Airframe' it fails. Why??

Hii Bentolila Yedida,

I understand you are unable to change the gain parameter for a subsystem inside 'Airframe'.

The 'set_param' function allows you to modify parameters of Simulink blocks, including subsystems.To change a parameter value inside a subsystem that is nested within another subsystem, you need to specify the full path to the parameter you wish to modify.

Here's an example that describes the condition:-

set_param('Model/Airframe/SubsystemName','Gain','Value ');

For better understanding of the 'set_param', kindly refer to following link:-https://in.mathworks.com/help/simulink/slref/set_param.html

Thanks Dlya, I did specify the full path to the parameter! For some Subsystems it works for other it does not?? I cannot understand whats the differences between these subsystems

[Bentolila Yedidia]

OK I found the problem: The Name of the Subsystem. Sometimes when entering the name we leave a blank space (at beginning or at the end) which cannot be easily noticed. Only by Checking in 'Properties' we can see the mistake.

Hope this did solve your problem!
