摘要:

本文提出有界动态(但无观测器)的输出反馈律,实现简化年龄结构化学培养皿PDE模型平衡态的全局稳定化。化学培养皿PDE状态为正值,这意味着我们的全局稳定化是在特定函数空间的正交ant中建立的——一种非标准的情况,为此我们开发了非标准工具。我们的反馈律不使用任何模型的(分布式)参数知识。此外,我们为年龄结构化学培养皿PDE模型提供了一族高度非传统的控制Lyapunov函数(CLFs)。提供了两种类型的反馈稳定器:具有连续调整输入的稳定器和采样数据稳定器。结果基于将一阶双曲偏微分方程转换为常微分方程(一维)和积分延迟方程(无限维)。还提供了积分延迟方程的新稳定性结果;这些结果具有独立价值,允许显式构造年龄结构化学培养皿模型的CLF。

英文摘要:

We present bounded dynamic (but observer-free) output feedback laws that achieve global stabilization of equilibrium profiles of the partial differential equation (PDE) model of a simplified, age-structured chemostat model. The chemostat PDE state is positive-valued, which means that our global stabilization is established in the positive orthant of a particular function space-a rather non-standard situation, for which we develop non-standard tools. Our feedback laws do not employ any of the (distributed) parametric knowledge of the model. Moreover, we provide a family of highly unconventional Control Lyapunov Functionals (CLFs) for the age-structured chemostat PDE model. Two kinds of feedback stabilizers are provided: stabilizers with continuously adjusted input and sampled-data stabilizers. The results are based on the transformation of the first-order hyperbolic partial differential equation to an ordinary differential equation (one-dimensional) and an integral delay equation (infinite-dimensional). Novel stability results for integral delay equations are also provided; the results are of independent interest and allow the explicit construction of the CLF for the age-structured chemostat model.
