Generate Figure 6-18:
tvec=0:(140/99):140;
compare(syscl,sysclr,tvec,{type=7})
f18=plot({keep,legend=["original","reduced"]})
Figure 6-18. Step Response with fracred
The end result is comparable to that from wtbalance( ) with option
"match".
We can create a table to examine the values of the Hankel singular values
based on different decompositions approaches.
set precision 3 # Optional:
set format fixed # we set a smaller precision here so we
could fit
# the table in the manual.
[syscr, hsvrs] = fracred(sys, Kr, Ke, "right stab",2);
[syscr, hsvls] = fracred(sys, Kr, Ke, "left stab",2);
[syscr, hsvrp] = fracred(sys, Kr, Ke, "right perf",2);
[syscr, hsvlp] = fracred(sys, Kr, Ke, "left perf",2);
