Abstract

This paper is devoted to the iterative interval estimation for nonlinear discrete-time systems. To reconstruct the system state, a sequence of iterative observers is established based on the iterative disturbance estimation and measured output. By means of the Lipschitz condition and [Formula: see text] technique, sufficient conditions are built by the Lyapunov function method to make observation errors convergent. Resorting to the zonotope-based reachability analysis, the reachable set of nonlinear terms and observation errors are analyzed such that the state interval can be supplied. The presented approach is validated by a simulation comparison.

非线性离散时间系统的迭代区间估计方法

本文致力于非线性离散时间系统的迭代区间估计。为了重构系统状态，根据迭代扰动估计和测量输出建立了一系列迭代观测器。通过 Lipschitz 条件和[公式：见正文]技术，利用 Lyapunov 函数方法建立了使观测误差收敛的充分条件。通过基于区顶的可达性分析，分析了非线性项和观测误差的可达集，从而可以提供状态区间。所提出的方法通过模拟比较得到了验证。

The Journal of Systems and Control Engineering refleSystems and control studies provide a unifying framework for a wide range of engineering disciplines and industrial applications. The Journal of Systems and Control Engineering reflects this diversity by giving prominence to experimental application and industrial studies. "It is clear from the feedback we receive that the Journal is now recognised as one of the leaders in its field. We are particularly interested in highlighting experimental applications and industrial studies, but also new theoretical developments which are likely to provide the foundation for future applications. In 2009, we launched a new Series of "Forward Look" papers written by leading researchers and practitioners. These short articles are intended to be provocative and help to set the agenda for future developments. We continue to strive for fast decision times and minimum delays in the production processes."
