Simulink 'integrator' doesn't integrate.

I'm not good at english. Sorry.

I made simulink file to control blade angle.

These dynamics are nonlinear.

I made like this.

And I saw under-right scope.

second 'integrator' works very well

but look second, third scope. They should be integration relation.

but look like just multiple gain.

why this situation happen??

Kindly attach your Simulink model to help resolve the issue effectively.
