System is continuous
7.
Frequency-weight the control signal.
Transfer the weight on
U
from
RUU
to the third diagonal entry in
RXXA
.
Note
In Equation 4-3, u is the third state of the augmented system.
RUU
weighs the new
frequency-shaped control signal v.
Design a frequency-shaped regulator:
rxxa=diagonal([0,1,1,0]);ruua=1;
[Sysfs_sr,,fs_evr]=fsregu(Sysa,2,rxxa,ruua)
Sysfs_sr (a state space system) =
