Finite-dimensional output stabilization for a class of linear distributed parameter systems -- a small-gain approach

Lars Grüne, Thomas Meurer

摘要:

提出了一种小增益方法来分析线性扩散反应系统在有限维状态反馈控制下的闭环稳定性。为此,考虑将无限维系统分解为用于设计的有限维慢子系统和无限维剩余快子系统。观察员溢出的影响,在一个特定的(动态)互连的子系统进行了彻底的分析,在域和边界控制以及传感。这导致应用的小增益定理的基础上的输入输出稳定性和无界可观性的互联系统。此外,提出了一种方法用于计算所需的尺寸的慢子系统用于控制器的设计。标量和耦合线性扩散反应系统的模拟方案被用来强调理论评估,并深入了解所产生的互联系统的属性。

英文摘要:

A small-gain approach is proposed to analyze closed-loop stability of linear diffusion-reaction systems under finite-dimensional observer-based state feedback control. For this, the decomposition of the infinite-dimensional system into a finite-dimensional slow subsystem used for design and an infinite-dimensional residual fast subsystem is considered. The effect of observer spillover in terms of a particular (dynamic) interconnection of the subsystems is thoroughly analyzed for in-domain and boundary control as well as sensing. This leads to the application of a small-gain theorem for interconnected systems based on input-to-output stability and unbounded observability properties. Moreover, an approach is presented for the computation of the required dimension of the slow subsystem used for controller design. Simulation scenarios for both scalar and coupled linear diffusion-reaction systems are used to underline the theoretical assessment and to give insight into the resulting properties of the interconnected systems.
