摘要

一项单独的研究解决了非线性系统单侧Lipschitz (OSL)族的执行器故障重构。该工作中预测的故障向量没有提供对系统潜在的有问题的物理特征的任何洞察，这是一个重大的缺点。在这项工作中，我们提供了一种使用自适应观测器策略估计执行器不正确物理参数的方法。为了证明该方法的有效性，给出了一个数值算例和仿真研究。

Actuator Fault Reconstruction for a Class of OSL Nonlinear Systems

A single study has addressed actuator failure reconstruction for the One-sided Lipschitz (OSL) family of nonlinear systems. The predicted fault vector in that work does not provide any insight into the underlying problematic physical characteristics of the system, which is a significant shortcoming. In this work, we offer a way for estimating the incorrect physical parameters of actuators using an adaptive observer strategy. To demonstrate the utility of the suggested method, a numerical example and simulation research are provided.
