abstract
The Generalized Predictive Controller developed in this research employs the models mentioned in Part I to calculate future changes in manipulated variables. Physical constraints of the continuous fryer were also imposed on the controller. These restrict the inputs to a certain range regardless of the optimal value. A tracking test was designed using typical industry values. The output setpoints were changed to see how well the inputs tracked the variation. The response time was adequately short. The input variations were within industry standards. The yielded output signals were smooth and showed little or no overshoot for the different setpoint changes.
