3.5 The block diagram of an autopilot designed to maintain the pitch attitude of an aircraft is shown below. The transfer function relating the elevator angle de and the pitch attitude is e(s) 50(s + 1)(s +2) G(8) 8e (8) (52 +58 +40)(52 +0.03s +0.06) where 0 is the pitch attitude in degrees and de is the elevator angle in degrees. The autopilot controller uses the pitch attitude error e to adjust the elevator according to the transfer function 8e(s) K(+3) D(s) s +10 Using MATLAB, find a value of K that will provide an overshoot of less than 10% and a rise time faster than 0.5 sec for a unit-step change in Or.
