Abstract

The presence of faults in a system leads to a lower value for efficiency, accuracy and speed, and, in some cases, even a complete breakdown. Thus, early fault detection is a major factor in efficiency and productivity of the procedure. In recent decades, many research studies have been conducted on troubleshooting and secondary fault detection. The current work presents an efficient and novel observer design capable of stabilizing the residue and dynamic error for the nonlinear Lipschitz systems with faults as well as a troubleshooting analysis and determining the formation of secondary faults in defective systems. The observer is designed based on linearizing dynamic error considering uncertainty, disturbance, and defects by employing non-linear gain factors instead of using state transformation. The dynamic error and residue stabilization of a non-linear faulty system have been discussed as well as the likelihood of secondary fault generation. The results indicate that the observer is able to determine fault-emergence, fault-disappearance and secondary fault formation well and quite fast.

考虑动态误差的线性化，设计了非线性lipschitz系统的有效观测器来排除和检测二次故障

系统中故障的存在会导致效率、准确性和速度的降低，在某些情况下甚至会导致完全的故障。因此，早期故障检测是提高程序效率和生产率的主要因素。近几十年来，人们对故障排除和二次故障检测进行了大量的研究。本文提出了一种有效的、新颖的观测器设计，能够稳定带有故障的非线性Lipschitz系统的残差和动态误差，以及故障排除分析和确定缺陷系统中二次故障的形成。该观测器是基于考虑不确定性、干扰和缺陷的线性化动态误差设计的，采用非线性增益因子代替状态变换。讨论了非线性故障系统的动态误差和剩余镇定问题以及二次故障发生的可能性。结果表明，观测器能够很好、很快地判断出断层的出现、消失和次级断层的形成。
