Abstract :
A practical approach for improving tracking performance of the predictive functional control is proposed. The disturbance observer is utilized to reduce the prediction error in the PFC algorithm and cope with high-order disturbances. The proposed control scheme is experimentally validated on a single axis table drive system and is compared with the standard PFC and the industrial cascade control. The experimental results prove the effectiveness of this disturbance observer-based PFC scheme.
