“…However, it is gratifying that the adaptive faulttolerant control approach can solve this kind of hybrid actuator faults [40][41][42]. As a matter of fact, the adaptive fault-tolerant control approach, as a branch of AFTC, can compensate for the failures well by reconstructing a new controller online by forming a suitable fault-tolerant control law (for details, see [29,31,[33][34][35][36][37][40][41][42][43] and references therein), which is the second motivation of this paper. e purpose of this paper is to design an adaptive faulttolerant controller for NSUSVs that suffer from external disturbance and multiple types of actuator faults.…”

This paper aims to design an asynchronous adaptive fault-tolerant controller for the networked stochastic unmanned surface vehicles (NSUSVs) subject to multiple types of actuator faults and external disturbance. The partial fault and bias fault of the actuator are taken into consideration simultaneously. By estimating online the unknown bias fault of the actuator and the external disturbances, the proposed adaptive fault-tolerant controller can automatically compensate for these impacts produced by actuator faults and external perturbation while preserving the uniformly ultimate boundedness of the solutions. Both the faulty actuator and the designed controller are asynchronous with the NSUSVs. Moreover, a mode-dependent adaptive event-triggered mechanism (AETM) is introduced in order to facilitate network resources utilization. Finally, the effectiveness and correctness of the proposed design scheme are verified by a numerical example.

“…In practice, the multi‐agent systems would likely suffer from faults due to the unknown abrupt phenomena. Several excellent research results have been reported on fault‐tolerant control (FTC) problem, include passive FTC and active FTC, see References 24‐30 and their associated references. More specially, a FTC strategy for multi‐agent systems was proposed in Reference 31, the controller was composed of a healthy controller and an estimator to predict fault severity.…”

This article investigates the output fault-tolerant consensus problem for multi-agent systems with switching topology and deception attacks. In order to reduce the effects of switching topology, the differences between topologies can be modeled as topology uncertainties. In practice, the deception attack may occur in a random way and assumed to satisfy Bernoulli distributions. The purpose of this research is to design an output fault-tolerant controller such that, in the presence of switching topology, actuator faults, and deception attacks, the finite-horizon output fault-tolerant consensus can be achieved under a prespecified H ∞ performance. An initial-state-based performance requirement is constructed, and this bypasses the need for the zero initial condition in the conventional H ∞ theory. After this, the controller gains are computed by employing an iterative linear matrix inequality scheme. Finally, a numerical example is provided to show the effectiveness of the proposed methods.

“…Actuator is a crucial component in control systems, and without proper control methods, even a minor actuator failure can result in unsatisfactory performances of the system and even catastrophic consequences. In order to mitigate the impact of failures and ensure the reliability of the entire system, there are increasing concerns about the reliable controller's design with actuator failures, such as References 30‐37 and the references therein. Obviously, the above references only consider partial fault (loss of effectiveness) of the actuator.…”

Summary This article studies a kind of asynchronous fault‐tolerant control problem for stochastic systems (Markov jump systems, MJSs) with multiple‐types of actuator failures. Both the loss of effectiveness and stuck fault of actuator are taken into consideration in a unified actuator failures model. The asynchronization phenomenon between the controller and the original system is described by a hidden Markov model. By coupling the unknown stuck fault of actuator and the external disturbances together, the stuck fault and disturbance can be estimated simultaneously. After this, a fault‐tolerant controller based on the estimated values is designed further to automatically compensate for the faults while preserving the uniformly ultimate boundedness of the solutions. Moreover, a mode‐dependent adaptive event‐triggered mechanism is introduced to limit the number of packets sent on the network. Finally, a numerical example is employed to illustrate the effectiveness of the proposed design scheme.
