Identification of simple mass balance models for plant growth - evolving yields and incorporating developmental stages

摘要: This paper presents a simple mass balance model for plant growth. basis is in the development of intended to enable prediction and control production chamber MELiSSA, regenerative life support system project developed by ESA. Photosynthesis respiration have been selected as key reactions biomass production. Considering these reactions, was using approach. Reaction kinetics were chosen based on physiology standard biochemical reaction knowledge. The identification validation yield kinetic parameters performed data from lettuce beet experiments closed chamber. Although adequately predicts growth, oxygen can be improved considering two stages photosynthetic quotient.
