 % Implementation of the data-driven approach for (Feedforward) LPV systems. 
 %
 % [System] Must specify the model, frequency grid and initial controller. 
 % See an example in the RotaryLPV.m file. The model must be able to be
 % evaluated at the specified frequency grid w using freqresp(xxx,w).
 %
 % [objectives] Entries of this structure must be able to be evaluates at
 % the speficied frequency grid w using freqresp(xxx,w). Note that for
 % feedforward only objectives on the tracking error are implementend, ie
 % objectives.two.W1 and objectives.inf.W1.
 %
 % [constraints] Entries of this structure must be able to be evaluates at
 % the speficied frequency grid w using freqresp(xxx,w)
 %
 % [parameters] If the stability constaints are not needed (dangerous, but
 % time saving), set parameters.radius=0 and parameters.robustNyquist=0.
