Description of folders:
* Basic simulation: 
The standard configuration. Mol concentration of MeOH (x_MeOH) is controlled using air flow and total flow is controlled using MeOH flow. 
Air flow reaches its maximum and you loose control of x_MeOH

* Compressor_test:
loop with the compressor. you can have a set point for the air flow.
the static part of the compressor is the compressor map.

* Open loop tests: 
Similar to Basic simulation_dynamic_mixer. This is to "play" more with the model, without messing up with it. There might be slight differences in tuning. 

* Others_not used:
Other files. I tried to implement a motor for the dynamics of the compressor. However, there are some sizing parameters that have to be defined and I decided to not continue investing time in that. 

* TPM_change simulation:
The difference wrt "Basic simulation_dynamic_mixer" is that the TPM is switched. 
Now, (x_MeOH)  is controlled using MeOH flow and the total flow is controlled using m_air
When air flow reaches its maximum, you keep control of x_MeOH, but loose control of m_tot. 

* Valve_test
loop with valve, including actuator.
