Abstract
This paper describes about disturbance observer (DOB)-based predictive functional critical control (PFCC). Generally PFC couldn't handle constraint on controlled output. A few techniques have been proposed but they have each drawback. We propose new control method using critical control for handling constraints. This approach does not increase on-line computational burden. In this paper, we design critical control for disturbance observer based PFC. The effectiveness of the proposed method is checked through an experimental evaluation. Constrains are imposed on the tracking error and controller output.
