Wind turbines are playing an increasingly important role in renewable power generation. Their complex and large-scale structure, however, operation remote locations with harsh environmental conditions highly variable stochastic loads make fault occurrence inevitable. Early detection location of faults vital for maintaining a high degree availability reducing maintenance costs. Hence, the deploy...

The nonlinear interconnected system is a complex and important in daily production life general. Due to the interconnection influence between subsystems external disturbance factors, prone failure. For this kind of system, decentralized fault detection tolerant control method proposed here. Compared with traditional scheme, paper designs subsystem communication protocol reduce information excha...

In this paper, a bibliographical review on reconfigurable (active) fault-tolerant control systems (FTCS) is presented. The existing approaches to fault detection and diagnosis (FDD) and fault-tolerant control (FTC) in a general framework of active fault-tolerant control systems (AFTCS) are considered and classified according to different criteria such as design methodologies and applications. A...

We investigate a novel adaptive fault-tolerant control method for time-varying failure in high-speed train computer systems and propose a fault model for such systems. First, the dynamics of high-speed train systems are analyzed and a multiple point-mass model is developed. When actuator outputs deviate from the expected value, a novel adaptive fault-tolerant control method based on Lyapunov st...

This paper presents an adaptive fault-tolerant control (FTC) scheme for leader-follower consensus control of uncertain mobile agents with actuator faults. A local FTC component is designed for each agent in the distributed system by using local measurements and certain information exchanged between neighboring agents. Each local FTC component consists of a fault detection module and a reconfigu...

In this paper, it is presented a fault-tolerant system based on output feedback H∞ Markovian control for manipulator robots. Firstly, it is shown that with a control strategy based on deterministic nonlinearH∞ approach the stability is guaranteed only if the robot stops completely after the fault detection, and then restarts the movement from zero velocity in an underactuated configuration. Sec...

This paper considers fault-tolerant control (FTC) for constrained linear systems subject to partial actuator failures. An active fault-tolerant control scheme based on model predictive control (MPC) and fault detection and isolation (FDI) is proposed. The FDI module using a two-stage Kalman filtering algorithm provides simultaneous control parameter and state estimation, which are used to modif...

Research in the area of fault-tolerant distributed systems has focused to a large extent on data surviving various forms of failure. The replica control algorithms for maintaining mutually consistent replicas abound in number. However, comparatively little work has been devoted to making processes recoverable. In domains other than databases and transaction processing, faulttolerance generally ...

In this paper, we investigate the robust fault-tolerant finitetime stabilization problem of switched system with asynchronous switching. The asynchronous switching idea originates from the fact that switching instants of the controllers lag behind or exceed those of subsystems. The attention is focused on designing a robust fault-tolerant asynchronously switched controller that guarantees the f...

The fault-tolerant control scheme utilizes grouping of currents to reduce the required number of controller outputs. Reduced current distribution matrices can be calculated with the constraint conditions of the controller outputs and the necessary condition for linearization. Decoupling chokes are not required for the control scheme with grouped currents since fluxes are isolated in C-cores. By...
