Adaptive fault‐tolerant formation control for quadrotors with actuator faults [PDF]
Asian Journal of Control, 2019 AbstractIn this paper, we investigate the fault‐tolerant formation control of a group of quadrotor aircrafts with a leader. Continuous fault‐tolerant formation control protocol is constructed by using adaptive updating mechanism and boundary layer theory to compensate actuator fault.

Fault Tolerance for Active Surface System with Actuator Faults [PDF]
Advances in Astronomy, 2021 The QiTai Radio Telescope (QTT) will be equipped with the active surface adjustment system (ASAS) to correct the main reflector deformation caused by environmental loading. In order to guarantee the stability and performance of the active surface system under fault conditions, it is necessary to adopt the fault-tolerant method when actuator faults have

Active fault tolerant control for nonlinear systems with simultaneous actuator and sensor faults [PDF]
, 2013 The goal of this paper is to describe a novel fault tolerant tracking control (FTTC) strategy based on robust fault estimation and compensation of simultaneous actuator and sensor faults. Within the framework of fault tolerant control (FTC) the challenge

CONTROLLERS FOR FAULT TOLERANT ACTUATORS
Aviation, 2007 The Fly‐by‐Wire technology enables flexible shaping of both effective dynamics and handling qualities of aircraft. This solution extends aircraft possibilities and supports the pilot by use of high‐level control laws. Application of FBW for aircraft would make flying both safer, and more popular. On the other hand the FBW system must be highly reliable.

Reliable fault-tolerant model predictive control of drinking water transport networks [PDF]
, 2016 This paper proposes a reliable fault-tolerant model predictive control applied to drinking water transport networks. After a fault has occurred, the predictive controller should be redesigned to cope with the fault effect.

Comments on actuator fault accommodation [PDF]
IFAC Proceedings Volumes, 2009 The present work concerns the problem of progressive accommodation to actuator failure. An optimal nonlinear controller synthesis approach is formulated on the basis of the closed loop stability objective. The authors show the interest of the proposed method even for a local analysis when a linear approximation is used.

Adaptive fault tolerant control against actuator faults
International Journal of Adaptive Control and Signal Processing, 2016 SummaryThis paper investigates the problem of adaptive fault tolerant control for a class of dynamic systems with unknown un‐modeled actuator faults. The fault model is assumed to be an unknown nonlinear function of control input, not in the traditional form in which the faults can be described as gain and/or bias faults.
