Hi I want to generate a signal as a load follow input signal for 80%-50%-80% at 10% per minute for a nuclear power plant control system on simulink? I would be glad for help because i am stucked at this stage?

The signal is attached. Thank you 

[Birdman]

Do you want to create the input signal in the figure?

[KaMATLAB]

Yes! I have been struggling with it Thank you

Answer 1

[Birdman]

Run the attached model. I used Signal Builder block to create the input signal.

[KaMATLAB]

Ok thank you i will try it now

[Birdman]

Try and let me know the result.

[KaMATLAB]

i got an error attached

[Birdman]

I didn't have any variable called tuvar. How are you using the model?

[KaMATLAB]

I run it on the simulink and it returned the error. I am running R2014a

[Birdman]

I am attaching the 2014a version of the model. Just open the model and run it. Open the Scope to see the result. Do not do any change in the model.

[KaMATLAB]

I had been trying to create it with signal builder before i sought for help. Find attached my effort but could not achieve it

[Birdman]

Don't try to create it yet. Firstly, run the attached Signal_R2014a model and see the result.

[KaMATLAB]

ok thank you

[KaMATLAB]

It is fine now! Please can put me through how you get it done? Because i may want to change the signal during my simulation practices? thank you You are da bomb

[KaMATLAB]

Hey! Please can you help me on the procedure please. I need to simulate several of the load cases. Thank you

[Birdman]

In the attached figure explanation1, you see that you can set the T and Y value of that specific point by either changing the value in T and Y edit field, or by just simply dragging that specific point.

In the attached figure explanation2, you can create a new piece of line by simply dragging upwards or downwards the circled line and then again, you can set its starting and end points.

Thank you very much. you really made my day
