Changing the firing angle using a pulse generator on simulink (Matlab)

[SarahT]

I'm building a model on simulink and need to change the firing angle using the pulse generator block. The firing angles that I require are 30, 45 and 60 degrees.
I have also attached and image of my circuit.

Any help will be appreciated,
Kind regards, Sarah
