What Results from Applying Conventional Controllers to MATLAB Neural Network Demos

It is shown that appropriate conventional controllers applied to strongly nonlinear plants taken from MATLAB Neural Network (NN) Control Systems Demos are significantly better than NN controllers appearing in these Demos. Moreover the conventional controllers operate well for significantly larger changes of the reference signal without the need of their re-tuning. The applied conventional controllers fulfill the demands of formulated in the present paper the Criterion RD1 (Relative Degree =1).
