I need help with parts b and c. thanks!

 

Hints:
dr (t)
In part (c), use two control (input) variables: u1 = r(t) and u2 =
dt
In part (d), you are given a system of two coupled differential equations where the state
variables are 0(t) (pitch angle) and a(t) (angle of attack), and the control is &e(t)
(elevator deflection).
