Special Issue Information

Dear Colleagues,

Modern products and systems are always desired to be highly reliable. As a result, reliability engineering becomes an important subject, with research on improving product reliability. The purpose of this Special Issue is to show and share new ideas and achievements of reliability estimation approaches, reliability prediction methods, reliability design tools, and related applications in engineering practices with relevant experts, scholars, and engineers around the world. Symmetric and asymmetry properties are commonly inherent in numerous physical and engineering systems, and have been studied by various researchers. We would like to invite experts to contribute their research by employing symmetry or asymmetry concepts in their methods and methodologies. The topics of this Special Issue include, but are not limited to, the following: prognostics and health management, failure mechanism analysis, degradation modeling, reliability estimation, fault-tolerant control, fault diagnosis, health management, network reliability analysis, maintenance strategy, and digital twins. Manuscript types include original research papers, reviews, and letters.

Abstract
This paper presents a concomitant observer-based multi-level fault-tolerant control (FTC) for near-space vehicles (NSVs) with a new type dissimilar redundant actuation system (NT-DRAS). When NSV flight control system faults occur in NT-DRAS and attitude-corresponding sensors, the NSV hybrid output states, including the concomitant [...] Read more.
This paper presents a concomitant observer-based multi-level fault-tolerant control (FTC) for near-space vehicles (NSVs) with a new type dissimilar redundant actuation system (NT-DRAS). When NSV flight control system faults occur in NT-DRAS and attitude-corresponding sensors, the NSV hybrid output states, including the concomitant observer usable states and the real system states, are applied to solve the FTC gain by using the linear quadratic regulator (LQR) technique. Furthermore, since NT-DRAS is used in NSVs, a multi-level (actuation system level and flight control level) FTC strategy integrating NT-DRAS channel switching and flight control LQR is proposed for complex and worsening fault cases. The most important finding is that though the proposed strategy is applicable for worsening fault cases in NSVs, systematic and accurate criteria for the process being performed are necessary and can improve the FTC efficiency with minimal FTC resources. Additionally, such criteria can improve the NSV’s responsiveness to comprehensive faults, provided that the real-time performance of the fault detection and diagnosis (FDD) scheme can be further optimized. The concomitant observer convergence and the multi-level FTC strategy have been verified by numerical simulations based on the Matlab/Simulink platform. Full article

In this paper, a practical maintenance algorithm is proposed to improve the reliability of actuation systems and their components, specifically addressing the consistency degradation caused by faults in the symmetric actuation system components of more electric aircraft (MEA). By integrating important measures with traditional genetic algorithms, the accuracy of the algorithm is improved. Prior to maintenance, a reasonable classification of components is built to mitigate the adverse effects of extreme fault conditions on the algorithm. This approach improves both the effectiveness and efficiency of the algorithm, rendering the overall maintenance strategy better suited for real-world needs. Finally, comparative simulations confirm the algorithm’s superior performance in reliability improvement, demonstrating its substantial contribution to the field of MEA maintenance and reliability.
