Create an option set for the h2syn command that turns off automatic regularization of the plant. Turning off regularization can speed up the computation when you know your problem is far from singular.
You can use Name,Value pairs to create the option set.
opts = h2synOptions('Regularize','off');
Alternatively, create a default options set and use dot notation to change the option value.
opts = h2synOptions;
opts.Regularize = 'off';
You can now use opts as an input argument to h2syn.
Specify optional
comma-separated pairs of Name,Value arguments. Name is
the argument name and Value is the corresponding value.
Name must appear inside quotes. You can specify several name and value
pair arguments in any order as
Name1,Value1,...,NameN,ValueN.
Automatic plant scaling, specified as the comma-separated pair consisting of
'AutoScale' and one of the following:
'on' — h2syn automatically scales the
plant states, controls, and measurements to improve numerical accuracy.
h2syn always returns the controller K
in the original unscaled coordinates.
'off' — h2syn does not change the
plant scaling. Turning off scaling when you know your plant is well scaled can
speed up the computation.
Example: opts = h2synOptions('AutoScale','off') creates an
option set for h2syn that turns off automatic
scaling.
Automatic regularization of the plant, specified as the comma-separated pair
consisting of 'Regularize' and one of the following:
'on' — h2syn automatically regularizes
the plant to enforce requirements on P12
and P21 (see h2syn). Regularization is a process
of adding extra disturbances and errors to handle singular problems.
'off' — h2syn does not regularize the
plant. Turning off regularization can speed up the computation when you know your
problem is far enough from singular.
Example: opts = h2synOptions('Regularize','off') creates an
option set for h2syn that turns off regularization.
