Abstract
Variable horizon predictor (VHP) background and design are discussed. VHP is designed to work in feedback control loops with various control algorithms, especially with processes featuring significant time delays. Disturbances are included into prediction, so there is no need to incorporate feedforward into feedback algorithms. PID and fuzzy logic controllers were tested with VHP and compared with simple predictive algorithm, developed to work with VHP. In all cases VHP proved to be flexible and efficient in improving control loop performance for dead-time dominant process control
