AER1202 Adv. Flight Dyn. & Control Assignment
Assignment #4, due Nov 22, 2019 9:00am
Based on the linearized longitudinal model of B747 (in Chapter 3, as well as in your Assignment
3)
1. (10 marks) design the pitch attitude control Ce through δe to satisfy the following specifi-
cations: 1) overshoot less than 20%, and 2) steady state error less than 10%.
2. (10 marks) design the speed control Cp through δp to satisfy the following specifications: 1)
overshoot less than 20%, and 2) steady state error less than 10%.
3. (20 marks) take your design to the following altitude hold control system, with the command
of hc = 45, 000 ft, Uc = 800 fps, design the proportional control law Kh, as well as taking
into account the actuator dynamics, where
Je =
1
Tes+ 1
, Te = 0.1, Jp =
1
Tps+ 1
, Tp = 3.5
again, to verify the system design specifications. If necessary, redesign the Ce and Cp.

Please provide details of design process/tuning efforts. Matlab design (.m) and Simulink simula-
tion (.slx) files shall be submitted together with design report.
