Hi,

The main idea in the previous post is how can I model in my west project, the real controller of the wastewater plant. That real controller is based on the NH4 .It’s composed of an on/off controller with Ymax=5mg/L and Ymin=3mg/L instructions. When NH4 exceeds 5mg/L a blower starts to supply 1250 m3/h of air flow, also after 2 min another blower starts to work in the same way to the first one (I want to simulate those blowers with an Aerator controller).



There is only one variable to control and it is NH4, the previous image it’s only an example of Layout, but in my case, I would like to change the DO variable with the NH4, because dissolved oxygen has nothing to do with my project.


Maybe the two blowers can be modelled as a blower with the aerator control. But the main problem is how to connect the control blocks with the corresponding variables.

Hello,
In my Project I would like to control NH4 in my aerobic tank, so as not to exceed the limit waste. That control consist in carry out the reduction of ammonia with an on/off controller with Ymax=5mg/L and Ymin=3mg/L instructions. Moreover, when Ymax exceeds the value, a pump starts, supplying 1250m3/h of air flow, also after 2 min an other pump starts to work in the same way to the first one. That happens only while Ymax>5mg/L, when it’s Ymax<5mg/L both pumps go off at the same time, furthermore when Ymin<3mg/L,  umin it’s 0.

My main problem is that, I don’t know exactly how to arrange the controller interface. I tried the disposition below, changing the DO variable for the NH4, and adding a control timer (located in the empty pin in the On/Off controller with T1=0 and T=2min as a variables). Also, as I told I put an on/off, instead of PI, moreover I don’t need the Avg and SRT calc elements (or I think so).

Could you help me in order to find the correct control arrangement in that layout?
Thanks in advance.
Delia.

Hello,

Yes, I am a student of Jaume I University .So, how can I get the Automation license?

Hello again.

We have a DHI Network license.
As I told you before we are following the pdf attached below, in particular the section called 'Integration of Tornado with MATLAB through .NET'.

Thank you,
Delia

Hello,
We are trying to link West 2016(x64) with Matlab(R2018b), using the following method: "Integration of Tornado with MATLAB through .NET" .
During the execution Matlab shows several errors:

- I | Loading license map spec: \etc\Keys.map|.Tornado
-I/O error: License map file cannot be opened: \etc\Keys.map | ..\..\..\..\src\Common\XML\XMLLicenseMap.cpp:76

Also, we would like to know,  while we are using the example 'TwoASU' what's the meaning of this variable: ' $(TORNADO_DATA_PATH) '  and this parameter: 'Tornado.main.xml' in the file generated in Matlab.

Thank you in advance,
Delia.
