Six criteria are offered for the evaluation of the performance of process controllers. Classical techniques for the design of PID controllers and modern control theoretic techniques for controller design are reviewed. It is shown that modern optimal

RA~SFER matrix models of process systems have been used. Tsuccessfully in linear multivariable feedforward control analysis (Bollinger and Lamb, 1962; Haskins and Sliepcevich,. 1965; T'erneuil, 1965). Hoivever, such models are inadequate for analytic
