Figure 4-5. Perfplots for Hew
It also is useful to perform perfplots( ) on the unweighted
closed-loop system, Hzv, which in this case is the closed-loop transfer
matrix from (d,n) into (x,u).
The following function calls produce Figure 4-6:
Hzv=clsys(G,K);
Hzv=perfplots(Hzv,1,1,{vF=domain(svHew)});
