自律分散制御に基づく環境制御システム

An Environmental Control System Based on the Decentralized Autonomous Control

An environmental control system proposed here was named the decentralized autonomous production management system (DAPMS). It was constructed based on the idea that each plant individual itself could require the desirable environment to the plant production equipments and growers to attach small computer chips. In the DAPMS, each plant individual is an element whose production state and goal are known. A potential function based on this information expresses how well the goals of each element are satisfied. The global discipline in the DAPMS was kept using the potential function in each plant individual. A simulation model of the DAPMS was developed to test this idea. In the simulation, different parts of the growing room were characterized by different environmental variables to reflect the situation in a real transplant production facility. Each plant individual was moved (for example, by a robot) to the place within the growing room that was best suited for its growth. A reasonable arrangement of the plant individuals was obtained by the DAPMS, even when changes were made in the scale of the facility, the number of plants, and other variables. The DAPMS was applied to cell tray production of sweetpotato transplants in a closed-type transplant production system. Even though the growing room had uneven environmental conditions and a variety of transplant individuals, the DAPMS was able to provide a desirable environment to the transplant individuals and to produce transplants with a uniform number of leaves.
