Glucagon pump control system

Hello,

I have to model a simple glucagon delivery system in simulink.

I am havaing trouble with what blocks to use and what values to input to them.

The exact question is,

create and simulate the above control system and using results from part b), show that the body glucose level response to a unit step input of Glucagon injection has the overshoot as calculated in part b) and peak time as calculated in part d)

Overshoot from part b is, 5% and was calculated to be 0.69

Peak time from part d is, 6 seconds

Pump time constant is, 0.5mins or 1 / 0.5s + 2

Any help woul;d be massively appriciated!

Thanks.
