4.2. A SIMPLE FLEXIBLE STRUCTURE EXAMPLE 177
A nominal response is calculated by setting ∆ = 0. To get the open-loop simulation
model we close the unweighted interconnection structure with a controller equal to zero.
deltazero = zeros(2,3)
Kzero = zeros(2,1)
nomolp = starp(deltazero,Pnom)
nomolp = starp(nomolp,Kzero)
yolp = nomolp*u
gph9 = ctrlplot(yolp(1,1));
gph9 = plot(gph9,{title="open loop beam length",...
ylab="micrometers"})?
