As with looptune, use the slTuner interface to configure the Simulink model for tuning.

Note that the signals of interest are already marked as Linear Analysis points in the

Simulink model.

ST0 = slTuner('rct_airframe2','MIMO Controller',op);

Try a second-order MIMO controller with zero feedthrough from e to delta fin. To do

this, create the desired controller parameterization and associate it with the "MIMO

Controller" block using setBlockParam:

C0 = tunableSS('C',2,1,2); % Second-order controller

C0.D.Value(1) = 0; % Fix D(1) to zero
