Yaw Damper for a 747 Jet Transport
9-19
Then close t he loop around the first I/O pair of the MIMO model sys and
simulate the impulse response.
cloop = feedback(sys,WOF,1,1);
% Final closed-loop impulse response
impulse(cloop,20)
Thebank angle response(output 2) dueto an aileron impulse(input 2) now h as
the desired nearly constant behavior over this short time frame. Although you
did not quite meet the damping specification, your design has increased the
damping of the system substantially and now allows the pilot to fly the aircraft
normally.
