Fault Tolerant Control for a class of non linear systems with dead zone
International Journal of Systems Science, 2016Co-Authors: Mou Chen, Bin Jiang, William W GuoAbstract:In this paper, a Fault-Tolerant Control scheme is proposed for a class of single-input and single-output non-linear systems with the unknown time-varying system Fault and the dead-zone. The non-linear state observer is designed for the non-linear system using differential mean value theorem, and the non-linear Fault estimator that estimates the unknown time-varying system Fault is developed. On the basis of the designed Fault estimator, the observer-based Fault-Tolerant tracking Control is then developed using the backstepping technique for non-linear systems with the dead-zone. The stability of the whole closed-loop system is rigorously proved via Lyapunov analysis and the satisfactory tracking Control performance is guaranteed in the presence of the unknown time-varying system Fault and the dead-zone. Numerical simulation results are presented to illustrate the effectiveness of the proposed backstepping Fault-Tolerant Control scheme for non-linear systems.

adaptive output feedback Fault Tolerant Control design for hypersonic flight vehicles
Journal of The Franklin Institute-engineering and Applied Mathematics, 2015Co-Authors: Bin Jiang, Jiasong QianAbstract:Abstract In this paper, an adaptive output feedback Fault-Tolerant Controller is developed for the longitudinal dynamics of a generic hypersonic flight vehicle in the presence of parameter uncertainties, actuator Faults and external disturbances. Firstly, the derivatives of the output are calculated repeatedly so that the relative degree of the system is obtained. Then feedback linearization is used to design the nominal Controller. Considering the occurrence of actuator Faults, a Fault-Tolerant Controller is developed based on the nominal feedback linearization Controller to accommodate the effect of actuator Fault, ensure system stability and recover desirable tracking performance. Since some of the states are difficult to measure during actual hypersonic flight, the high-gain observer technique is adopted to achieve output feedback Fault-Tolerant Control. Adaptive laws are designed for updating the Controller parameters when both the plant parameters and actuator Fault parameters are unknown. Closed-loop stability and output tracking performance are analyzed rigorously. Simulation results verify the effectiveness of the proposed adaptive Fault-Tolerant Control scheme.

decentralized asymptotic Fault Tolerant Control of near space vehicle with high order actuator dynamics
Journal of The Franklin Institute-engineering and Applied Mathematics, 2013Co-Authors: Bin Jiang, Peng Shi, Hongtao LiuAbstract:Abstract In this paper, a decentralized asymptotic Fault Tolerant Control system is proposed for near space vehicle (NSV) attitude dynamics. First, NSV reentry mode is described, and the actuator failure model is developed whose behavior is described by high-order dynamics. Next, the multi-model based Fault diagnosis and identification (FDI) algorithm is proposed for high order actuator dynamics, which can accurately diagnose and identify the Fault in short time. Based on sliding mode, command filter, and backstepping technique, using information of FDI, a constrained Fault Tolerant Control (FTC) is designed for reentry NSV. Finally, simulation results are given to demonstrate the effectiveness and potential of the proposed FTC scheme.

active Fault Tolerant Control design for reusable launch vehicle using adaptive sliding mode technique
Journal of The Franklin Institute-engineering and Applied Mathematics, 2012Co-Authors: Bin Jiang, Peng Shi, Moshu Qian, Zhifeng Gao, Jinxing LinAbstract:Abstract In this paper, the problem of active Fault Tolerant Control for a reusable launch vehicle (RLV) with actuator Fault using both adaptive and sliding mode techniques is investigated. Firstly, the kinematic equations and dynamic equations of RLV are given, which represent the characteristics of RLV in reentry flight phase. For the dynamic model of RLV in Faulty case, a Fault detection scheme is proposed by designing a nonlinear Fault detection observer. Then, an active Fault Tolerant tracking strategy for RLV attitude Control systems is presented by making use of both adaptive Control and sliding mode Control techniques, which can guarantee the asymptotic output tracking of the closed-loop attitude Control systems in spite of actuator Fault. Finally, simulation results are given to demonstrate the effectiveness of the developed Fault Tolerant Control scheme.

IFAC Proceedings Volumes, 2012Co-Authors: Moshu Qian, Bin Jiang, Hugh H T Liu, Zhifeng GaoAbstract:Abstract In this study, a new Fault Tolerant Control approach is proposed for a class of reusable launch vehicle (RLV) attitude Control systems. The nonlinear attitude Control systems of RLV are given, which represent the dynamic characteristics of RLV in ascent and reentry phases. When actuator loss-of-effectiveness (LOE) Faults occur, a new Fault Tolerant Control design is presented using the dynamic surface Control technique. Based on Lyapunov stability theory, the ultimate uniform boundedness of the Faulty attitude Control systems of RLV is analyzed. Finally, simulation results are given to illustrate the efficiency of the proposed approach.

design and analysis of an integral sliding mode Fault Tolerant Control scheme
IEEE Transactions on Automatic Control, 2012Co-Authors: Mirza Tariq Hamayun, Christopher Edwards, Halim AlwiAbstract:A novel scheme for Fault-Tolerant Control is proposed in this paper, in which integral sliding mode ideas are incorporated with Control allocation to cope with the total failure of certain actuators, under the assumption that redundancy is available in the system. The proposed scheme uses the effectiveness level of the actuators to redistribute the Control signals to healthy actuators without reconfiguring the Controller. The effectiveness of the proposed scheme against Faults or failures is tested in simulation based on a large transport aircraft model.

Fault Tolerant Control using sliding modes with on line Control allocation
Automatica, 2008Co-Authors: Halim Alwi, Christopher EdwardsAbstract:This paper proposes an on-line sliding mode Control allocation scheme for Fault Tolerant Control. The effectiveness level of the actuators is used by the Control allocation scheme to redistribute the Control signals to the remaining actuators when a Fault or failure occurs. The paper provides an analysis of the sliding mode Control allocation scheme and determines the nonlinear gain required to maintain sliding. The on-line sliding mode Control allocation scheme shows that Faults and even certain total actuator failures can be handled directly without reconfiguring the Controller. The simulation results show good performance when tested on different Fault and failure scenarios.

sensor Fault Tolerant Control using sliding mode observers
Control Engineering Practice, 2006Co-Authors: Christopher Edwards, Chee Pin TanAbstract:Previous work has considered the use of sliding mode observers for Fault detection and isolation (FDI) in uncertain linear systems whereby the unknown Faults are reconstructed by appropriate processing of the so-called equivalent output error injection. The paper builds on this work and considers such a scheme within the broader context of Fault Tolerant Control. Specifically, by correcting the Faulty measurement by an estimate of the Fault obtained from the sliding mode FDI scheme, good closed-loop performance is still maintained. An example of such a scheme, which has been implemented in real-time on a laboratory dc motor rig, is described.

Fault Tolerant Control systems a comparative study between active and passive approaches
Annual Reviews in Control, 2012Co-Authors: Jin Jiang, Xiang YuAbstract:Abstract This paper demystifies active and passive Fault-Tolerant Control systems (FTCSs) by examining the similarities and differences between these two approaches from both philosophical and practical points of view. Even though the Control objectives of both approaches are the same, each method uses its own unique ways to achieve the objectives. Therefore, different approaches can lead to seemingly different results. Advantages and limitations of each method are examined through at philosophical level as well as quantitative case studies using an aircraft flight Control system as a test system. A distinctive feature of this paper is that it provides an objective assessment of the two most popular Fault-Tolerant Control system design methodologies in an unbiased and comparative setting.

a stability guaranteed active Fault Tolerant Control system against actuator failures
International Journal of Robust and Nonlinear Control, 2004Co-Authors: Midori Maki, Jin Jiang, Kojiro HaginoAbstract:In this paper, a new strategy for Fault-Tolerant Control system design has been proposed using multiple Controllers. The design of such Controllers is shown to be unique in the sense that the resulting Control system neither suffers from the problem of conservativeness of conventional passive Fault-Tolerant Control nor from the risk of instability associated with active Fault-Tolerant Control in case that an incorrect Fault detection and isolation decision is made. In other words, the stability of the closed-loop system is always ensured regardless of the decision made by the Fault detection and isolation scheme. A correct decision will further lead to optimal performance of the closed-loop system. This paper deals with the conflicting requirements among stability, redundancy, and graceful degradation in performance for Fault-Tolerant Control systems by using robust Control techniques. A detailed design procedure has been presented with consideration of parameter uncertainties. Both total and partial actuator failures have been considered. This new Control strategy has been demonstrated by Controlling a McDonnell F-4C airplane in the lateral-direction through simulation. Copyright © 2004 John Wiley & Sons, Ltd.
