摘要

This paper presents a novel automation architecture for seamlessly making automated systems energy efficient while attaining its functional requirements. The architecture is multi-agent, ensuring the constellation of agents pursues energy optimality of the system, while working together on achieving functional requirements such as production goals. To ensure the industrial applicability of the agents, they were implemented as function blocks in IEC 61499 distributed automation architecture. The proposed solution was tested on a laboratory-scale model of assembly system consisting of six conveyors arranged in a circular configuration. Two experiments were conducted: one demonstrated the algorithm’s ability to track varying energy consumption setpoints, while in the other new workpieces were added into the system to verify stability in energy usage. Results show that the algorithm effectively regulates momentary energy demand without compromising system performance.
