Bioinspired design approaches seek to exploit nature in order to construct optimal solutions for engineering problems as uniform temperature control in multizone systems. The ideal free distribution (IFD) is a concept from behavioural ecology, which describes the arrangement of individuals in different habitats such that at equilibrium, all habitats are equally suitable. Here, we relax the IFD's main assumptions using the standing-crop idea to introduce dynamics into the supplies of each habitat. Then, we make an analogy with a multizone thermal system to propose a controller based on the replicator dynamics model, in order to obtain a maximum uniform temperature subject to constant power injection. Besides, we analytically show that the equilibrium point of the controlled system is asymptotically stable. Finally, some practical results obtained with a testbed and comparisons with the theoretical results are presented.
仿生设计方法旨在利用自然,为工程问题构建最优解决方案,例如多区域系统中的恒温控制。理想自由分布(IFD)是行为生态学中的一个概念,它描述了不同栖息地中个体的分布,使得在平衡时,所有栖息地都同样适宜。在这里,我们使用存量的概念放松 IFD 的主要假设,为每个栖息地的供应引入动力学。然后,我们将其与多区域热系统进行类比,提出基于复制者动力学模型的控制器,以在恒定功率注入的情况下获得最大均匀温度。此外,我们还进行了分析,证明了受控系统的平衡点是渐近稳定的。最后,我们展示了通过试验台获得的一些实际结果,并与理论结果进行了比较。
