Abstract
In this paper, we investigate uniform exponential stability approximation for a one-dimensional wave equation with potential. Given the challenges in identifying the time-domain multiplier for the exponentially stable continuous system, we opt for a frequency domain approach. Through the application of the order-reduction method, we devise a novel spatially semi-discretized finite difference scheme for the continuous system. We then establish the uniform exponential stability of the semi-discretized system using the discrete version of the frequency domain method, with the discrete proof mirroring the continuous case.
期刊介绍:
The European Control Association (EUCA) has among its objectives to promote the development of the discipline. Apart from the European Control Conferences, the European Journal of Control is the Association''s main channel for the dissemination of important contributions in the field.
The aim of the Journal is to publish high quality papers on the theory and practice of control and systems engineering.
The scope of the Journal will be wide and cover all aspects of the discipline including methodologies, techniques and applications.
Research in control and systems engineering is necessary to develop new concepts and tools which enhance our understanding and improve our ability to design and implement high performance control systems. Submitted papers should stress the practical motivations and relevance of their results.
The design and implementation of a successful control system requires the use of a range of techniques:
Modelling
Robustness Analysis
Identification
Optimization
Control Law Design
Numerical analysis
Fault Detection, and so on.
