Abstract : In this work the emphasis is on using simple models for the control of high-order processes. In Chapter 2 this approach is followed to tune continuous PI and PID control algorithms. In Chapter 3 the tuning of discrete controllers by using first-order plus dead time models was investigated. In addition to PI and PID controllers, attention was given to a deadbeat and a predictor algorithm. In Chapter 4 the extended Kalman filter was applied to the identification and control of first- and second-order discrete processes. In Chapter 5 the Kalman filter was used for identifying first- and second-order models of a heat exchanger. These models were used in a discrete control algorithm which attempts to achieve a setpoint response like the step response of a first-order process. (Author)
