Abstract : Design of a discrete optimal regulator requires the a priori knowledge of a mathematical model for the system of interest. Because a second order model with transport lag is very amenable to control computations and because this type of model has been used previously to represent high order processes, an adaptive controller was designed using an extended Kalman filter to track the model parameters which were subsequently used to update the optimal control gains. Favorable results were obtained for a third order process controlled using this model so as to minimize both a sum squared error index and a summed absolute error index. (Author)
