Yaw Damper for a 747 Jet Transport
10-5
pzmap(sys)
This model has one pair of lightly damped poles. They correspond to what is
called the “Dutch roll mode.”
Supposeyouwanttodesignacompensatorthat increasesthedampingof these
poles, so that the resulting complex poles have a damping ratio with
natural frequency rad/sec. You can do this using the Control System
toolbox analysis tools.
Open-Loop Analysis
