Abstract :
Doyle´s criticisms reveal significant misunderstanding of QFT. Doyle´s examples, claimed QFT incompatible, are done by QFT with vastly more economical loop compensators than Doyle´s designs. The QFT infinite frequency condition, charged as highly restrictive, is shown necessary for all linear time invariant (LTI) compensation techniques for achieving even moderate feedback benefits. In all available comparable designs, QFT has been more economical than other LTI ones.
