Simulink Problem in differential equation

Simulink Problem in differential equation

(OP)
I want to apply this equation on simulink.
alpha = omega * setta (as setta changes from 0 to 90 degree)

where:
setta :- angle.
omega :- angular velocity.
alpha :- angular acceleration.

I tried to make it So i made the following diagram
But I cannot insert values for setta!! So how to enter setta as changes from 0 to 90

RE: Simulink Problem in differential equation

Your equation is fundamentally incorrect. The units on both sides are not equal. Fix your equation, then try to create a Simulink model. If you have trouble, ask about the new model.

I am sorry the right equation is
alpha = omwga^2 / setta
The block diagram

but how to get values of omega and alpha when setta changes form 0 to 90

RE: Simulink Problem in differential equation

?? you show setta as the integral of omega, so there is not "setting" of setta. You've created a complete, self-contained, closed loop, You could possibly add a multiplier or sum box to inject a signal, but it wouldn't be setta, per se.

thnx you right i just did the initial conditions of setta and omega and it works
