Abstract

The paper deals with the problem of integrated fault estimation and fault tolerant control for constrained linear systems with bounded external disturbances. In particular, the above coupling causes that control and estimation influence each other. Thus, to prevent an unacceptable performance of the entire system, a new integration strategy is proposed, The proposed framework is based on an output feedback framework that consists of two stages: off-line – a low-complexity LMI-based optimization task and on-line – a deterministic model predictive control problem. The proposed approach is assessed using a cascade two-tank system example.

受输入和状态约束的离散系统的输出反馈集成容错控制

研究了具有有界外部干扰的约束线性系统的综合故障估计和容错控制问题。特别是，上述耦合导致控制和估计相互影响。因此，为了防止整个系统出现不可接受的性能，提出了一种新的集成策略，该框架基于输出反馈框架，该框架由两个阶段组成：离线-基于低复杂度lmi的优化任务和在线-确定性模型预测控制问题。最后以一个双罐系统为例对该方法进行了评价。

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.
