how to obtain pid output to 0 to 90 using automatic PID tunner

hi, i am designing closed loop pid controller for mean value engine model, for this model i am using pid controller in this model output of pid is always goes high i.e greeter than 90 but in our model input should be with in 0 to 90, how to make controller in such a way that it should give 0 to 90 values.

Are you talking about saturating your control signal? There are two options:

1-You can basically use a Saturation block from Simulink library and set its limits to 0 and 90.

2-You can use PID Controller's PID Advanced pane and there, you can activate saturation option and then again set the limits as you wish.

if saturation block is used then it take step type of input for increase or decreasing the reference input

I did not understand what you are trying to say.
