After designing the pitch controller, the anti-windup compensation was com-
puted by solving the optimization problem described in Sect.
5.2
. The optimiza-
tion problems for obtaining the H
?
controller and the anti-windup compensation
were solved using the Robust Control Toolbox for Matlab, Sedumi [
12
] and
YALMIP [
13
].
For the sake of comparison, a classical gain-scheduled PI controller was also
implemented and simulated. This PI, widely used in the literature as benchmark
