Based on the approach to model-based control design for an intraspecific competitive population system, the goal in this research project is to derive methods that lead to input-output models and controls based on them, for two coupled interspecific competitive population systems. Considering a single population, it has been shown that the population density, which can be controlled by the dilution rate, has an age structure fixed by the system parameters, which can only be influenced in amplitude over time. However, due to the different behaviors of the organisms depending on their age, it is desirable to influence this structure, for example, to maximize the metabolic activity of the total population at a given time. Therefore, the second grant periode will now investigate how this age structure can be influenced. It will be answered how the age structure is influenced by the coupling to a second population. The question is whether requirements can be made to the system parameters of a second species so that the age structure of the first species can be influenced in a desired way. Another option to influence the age structure, which will be investigated in this grant periode, is the recycling rate as a second control input. It will be answered how this additional dilution rate, which enters proportionally to the steady-state profile, affects the age structure.The remaining question is, in which way it is possible to extend the analytical solution methodology from the first grant period to two coupled population systems for the realization of control tasks. To what extent does the coupling influence the analytical approach to the system and which strategies can be used to find a system representation that allows the application of the methodology from the first grant period.The theoretical findings will be validated experimentally using a Permittistat-reactor. This reactor reflects a simplified realization of a variety of relevant applications such as wastewater treatment plants and bioreactors for protein synthesis. In terms of biological application, the investigation in the second grant period will allow to gain a deeper understanding of the system and to develop suitable approaches for model-based control of coupled population systems.

基于种内竞争种群系统的基于模型的控制设计方法，本研究的目标是针对两个耦合的种间竞争种群系统，导出导致输入-输出模型和基于模型的控制的方法。在考虑单个种群的情况下，可以由稀释率控制的种群密度具有由系统参数固定的年龄结构，这种结构只会随着时间的推移而变化幅度。然而，由于生物体的不同行为依赖于它们的年龄，因此希望影响这种结构，例如，在给定的时间使总种群的代谢活动最大化。因此，第二个授予周期现在将调查这种年龄结构如何受到影响。它将回答年龄结构如何受到与第二个人口的结合的影响。问题是，是否可以对第二个物种的系统参数提出要求，以使第一个物种的年龄结构能够以理想的方式受到影响。影响年龄结构的另一个选项是循环率作为第二个控制输入，这将在本赠款周期中进行调查。将回答这个与稳态分布成比例的额外稀释率如何影响年龄结构。剩下的问题是，如何可能将解析解方法从第一个授权期扩展到两个耦合的人口系统，以实现控制任务。耦合在多大程度上影响了对系统的分析方法，以及可以使用哪些策略来找到允许从第一个赠款期间起应用该方法的系统表示。理论研究结果将使用永久化反应堆进行实验验证。该反应器反映了各种相关应用的简化实现，例如用于蛋白质合成的废水处理厂和生物反应器。在生物应用方面，第二个赠款期间的调查将使人们能够更深入地了解该系统，并为耦合种群系统的基于模型的控制开发适当的方法。
