摘要

摘要针对一类具有时变未知参数和过参数化的线性系统，考虑了其状态重构问题，该系统受到具有未知初始条件的已知外系统产生的外部扰动的影响。与现有方法不同的是，本文提出了一种扩展自适应观测器，可以解决观测器典型形式无法表示的系统的状态和扰动自适应估计问题。通过数学建模验证了所获得的理论结果。

Adaptive Observer of State and Disturbances for Linear Overparameterized Systems

Abstract

The problem of state reconstruction is considered for a class of linear systems with time-invariant unknown parameters and overparameterization that are affected by external perturbations generated by a known exosystem with unknown initial conditions. An extended adaptive observer is proposed, which, in contrast to existing approaches, solves state and perturbation adaptive estimation problems for systems that are not represented in the observer canonical form. The obtained theoretical results are validated via mathematical modeling.

期刊介绍： Automation and Remote Control is one of the first journals on control theory. The scope of the journal is control theory problems and applications. The journal publishes reviews, original articles, and short communications (deterministic, stochastic, adaptive, and robust formulations) and its applications (computer control, components and instruments, process control, social and economy control, etc.).
