- Abstract
- Model predictive controller predicts the system performance and accordinglyimproves the controller performance. So it works well for time delayed systems. But the problemis that, it is not robust under certain cases. Sliding mode controller is robust but with a veryslow response rate. Its limitation is its delay handling capacity. In this paper, a predictivecontroller with good delay handling capability is combined with robust sliding mode controller.It is found to have a quick rise time and settling time with minimum overshoot. It is more robustand produced no oset, or oscillation. In this work, predictive sliding mode control is designedfor cylindrical, conical and cylindroconical bio-fermenter systems and their performances areanalysed. The controller is implemented in real time for a cylindrical system and a conicalsystem and it is found that the controller could handle delays and is also robust to parametervariations.
