IEC61131-3規格対応汎用PLCへのエッジ型モデル予測制御実装

抄録

In this paper, we propose a novel edge-type MPC which can be implemented on generic programmable logic controllers (PLCs) compliant to IEC61131-3 standard. The proposed method is composed of offline design and online control. The offline design is based on formula manipulation and the online control is based on a prediction filter with a plant model. The method can be applied to discretized-input cases such as on and off switching. We evaluated the method for an illustrative example of a chemical reactor. We show that real-time MPC on a generic PLC can be achieved via the example.
