Abstract
This paper addresses a two-degree-of-freedom control system design for positioning de-vices such as table drive systems based on the predictive functional control (PFC). The aim of the paper is to improve the tracking performance of the previously developed disturbance observer-based predictive functional control (DOB-PFC) system. To this end, we derive a transfer function representation of the PFC controller. On the basis of the representation, we apply the zero phase error tracking controller (ZPETC) as a feedforward preview controller. Experiments using a real table drive system are conducted to compare the proposed control system with DOB-PFC. The experimental results show that the tracking error is greatly reduced compared to DOB-PFC.
