Yaw Damper for a 747 Jet Transport

impulse(sys11,'b--',cl11,'r',20)
The closed-loop response settles quickly and does not oscillate much,
particularly when compared to the open-loop response.
Now close the loop on the full MIMO model and see how the response from the
aileron looks. The feedback loop involves input 1 and output 1 of the plant (use
feedback with index vectors selectingthis input/output pair). At the MATLAB
prompt, type
cloop = feedback(sys,-K,1,1);
damp(cloop) % closed-loop poles
