人造生态系统与其原型生物圈的不同之处在于控制原理。地球生物圈是通过随机控制和非常大的时间常数实现可持续发展的。相比之下，在封闭的生态系统中，例如欧洲航天局为太空探索开发的微生态生命支持系统替代方案（MELiSSA系统），确定性控制是可持续存在的先决条件。 MELiSSA 是互连生物子系统的综合体。一方面，研究负责构成整个生命支持系统的基本功能的所有单元操作，直到彻底理解和数学建模。另一方面，执行具有反馈循环的复杂、高度分支系统的系统方法。这导致在整合基于知识的控制模型之前，以相同的视角、相同的准确性和相同的语言研究废物降解、水循环利用、大气复兴和粮食生产系统。本文介绍了 MELiSSA 系统的数学建模以及整个系统的控制策略与生物反应器控制之间的接口。
Manmade ecosystems differ from their prototype biosphere by the principle of control. The Earth Biosphere is sustainable by stochastic control and very large time constants. By contrast, in a closed ecosystem such as the micro-ecological life support system alternative (MELiSSA system) developed by the European Space Agency for space exploration, a deterministic control is a prerequisite of sustainable existence. MELiSSA is an integrated sum of interconnected biological subsystems. On one hand, all unit operations in charge of the elementary functions constitutive of the entire life support system are studied until a thorough understanding and mathematical modelling. On the other hand, the systemic approach of complex, highly branched systems with feedback loops is performed. This leads to study in the same perspective, with the same degree of accuracy and with the same language, waste degradation, water recycling, atmosphere revitalisation and food production systems prior to the integration of knowledge-based control models. This paper presents the mathematical modelling of the MELiSSA system and the interface between the control strategy of the entire system and the control of the bioreactors.
