APPLYING FEEDBACK AND FEEDFORWARD CONTROL,
Abstract
Five topics concerned with applying feedback and feedforward control to chemical processes are considered. The first topic provides a comparison of tuning techniques. The results showed which modeling technique and tuning relations were best. The second topic considered was how to apply feedforward control. Overall this treatment provided a procedure for developing feedforward controllers. The third topic considered the use of search techniques to determine optimal switching times. The results showed that use of a search technique was superior to other theoretical approaches particularly for higher order batch processes. The fourth topic considered a comparison of optimal and suboptimal controllers. It was shown that for a given control problem, there is definitely a point of diminishing returns when adding state variables to the controller. The final topic considered the dynamic modeling and control of a distillation column. Theoretical and experimental models were developed and optimal feedback control theory and feedforward control theory were applied to the simulated distillation column. (Author)
