“…In some researches, the nonlinear system is linearzed or partially linearized [Schwung et al(2015)Schwung, Beck, and Adamy, Wei et al(2017)Wei, Qiu, Shi, and Wu,Li et al(2017)Li, Wang, Aitouche, Tian, and Christov,Ma et al(2018 Ma, Liu, Li, and Yang]. Silding-model observer (SMO) technique shows some effectiveness for fault estimation, as in a Takagi-Sugeno model Li, Wang, Aitouche, and Christov], a satellite attitude control system [Zhang et al(2013) Zhang, Swain, and Nguang], and an extended fixed-time SMO applied in FTC for an unmanned airship [Zhou et al(2022)Zhou, Li, Yang, Xu, Yu, and Zhang]. Adaptive observers [Zhang et al(2010) Zhang, Polycarpou, andParisini,Avram et al(2017)Avram, Zhang, andMuse,Chen et al(2020) Chen, Liu, Shi, Zhang, and Zhao] methods are also used to solve the nonlinear nature.…”

This paper is dedicated to investigating an observer-based fault diagnosis (FD) approach for a Lipschitz nonlinear system and applied in a stratospheric airship (SA) flight control system. The system model uncertainties, external disturbances, and sensor noise are considered. Firstly, a detailed model of the SA is obtained by kinematics and dynamics. Then a nonlinear fault detection observer is designed via Linear Matrix Inequation (LMI) in H∞ framework, and a bank of unknown input observers is activated for isolating the faulty component. Moreover, to estimate the size of the fault, an expanded robust estimation observer is designed concerning states and fault estimator error. All of the mentioned observers are designed by a matrix inequation formulation, which reformulated the nonlinear system to a generalized Linear Parameter Varying (LPV) system mathematically. The proposed FD scheme is applied to the control system of a SA and its effectiveness is illustrated. Mathematics Subject Classification (2020) MSC code1 · MSC code2 · more

“…Since then, fractional calculus has been introduced in several control schemes and methods such as sliding mode control [14], predictive control [15,16], and particularly adaptive control [17,18,19]. Recently, many research works have proposed Fault Tolerant Controllers using fractional order models in order to improve the efficiency and performance of the controlled plants [20,21].…”

In this paper, a comprehensive review of recent advances and trends regarding Fractional Order Fault Tolerant Control (FOFTC) design is presented. This novel robust control approach has been emerging in the last decade and is still gathering great research efforts mainly because of its promising results and outcomes. The purpose of this study is to provide a useful overview for researchers interested in developing this interesting solution for plants that are subject to faults and disturbances with an obligation for a maintained performance level. Throughout the paper, the various works related to FOFTC in literature are categorized first by considering their research objective between fault detection with diagnosis and fault tolerance with accommodation, and second by considering the nature of the studied plants depending on whether they are modelized by integer order or fractional order models. One of the main drawbacks of these approaches lies in the increase in complexity associated with introducing the fractional operators, their approximation and especially during the stability analysis. A discussion on the main disadvantages and challenges that face this novel fractional order robust control research field is given in conjunction with motivations for its future development. This study provides a simulation example for the application of a FOFTC against actuator faults in a Boeing 747 civil transport aircraft is provided to illustrate the efficiency of such robust control strategies.

This paper focuses on the fault diagnosis method and the fault‐tolerant control method of the aircraft with control surface damage. The fault diagnosis method is based on the set‐membership estimation. To diagnose the fault of control surface under the condition of data containing noise and uncertainty, a multi‐index optimized fault residual observer based on sensitivity and robustness is designed for the observation of aircraft fault information. Based on the observed fault residual information, the set‐membership estimation theory is used to determine whether the aircraft control surface fault occurs. The fault‐tolerant control method is based on dynamic inverse control via aerodynamic parameter identification. Furthermore, to reduce the nonlinear effects of unmodeled dynamics and aerodynamic identification errors after a fault, an adaptive disturbance rejection observer is designed for control compensation. The proposed methods are evaluated by numerical simulation. Results demonstrate that the fault diagnosis method can effectively diagnose under the influence of uncertain noise and the attitude control has the robustness of different faults.
