Fault Detection of Actuator Faults for Electric Vehicle

2007 IEEE International Conference on Control Applications, 2007
The main purposes of this paper concern: fault generation of nonlinear analytical redundancy for actuator faults of electric vehicle. These relations are used to detect and isolate actuator fault based on the elimination of the unknown variables of the system. Each residual, obtained by elimination theory, is sensitive to only one actuator fault thanks

Fault-tolerant control against stuck actuator faults

IEE Proceedings - Control Theory and Applications, 2005
A fault-tolerant control system (FTCS) design technique against stuck actuators is investigated using an iterative learning observer (ILO). The principle of the proposed fault-tolerant control (FTC) is to design a reconfigurable controller using estimated system states, relying on control input adjustments on the redundant actuators to compensate for ...

PROGRESSIVE ACCOMMODATION OF AIRCRAFT ACTUATOR FAULTS

IFAC Proceedings Volumes, 2006
Abstract In this paper, a fault tolerant control strategy based on the linear quadratic problem is proposed. The strategy progressively accommodates the feedback control law according to the iteration solutions of the Newton-Raphson algorithm. It significantly reduces the loss of system performance, which results from the time delay that is necessary

Fault-tolerant control for over-actuated systems with actuator fault and input saturation

2018 Chinese Automation Congress (CAC), 2018
This paper proposes a novel fault-tolerant tracking control strategy for over-actuated systems subject to actuator fault, control input saturation and external disturbance. The proposed method integrates the effect of actuator saturation and the actuator fault into a generalized disturbance.

Adaptive fault-tolerant tracking control against actuator faults

2006 American Control Conference, 2006
This paper deals with the problem of flight tracking control against actuator faults based on linear matrix inequality (LMI) method and adaptive method. The type of faults under consideration is loss of actuator effectiveness. An adaptive fault-tolerant flight controller design method is developed based on the on-line estimation of an eventual fault ...

Actuator Fault Tolerant PID Controllers

IFAC Proceedings Volumes, 2012
Abstract This paper deals with issues of actuator fault tolerant PID controllers. It is studied, how residual generation based on a linear model is affected by the robust properties of a PID used in feedback. To get the sensitivity of the residual with respect to faults and to keep the robustness of the controller, a scheme is proposed with a non ...

Sensor and Actuator Fault Reconstruction

Journal of Guidance, Control, and Dynamics, 2004
Many fault detection filters have been developed to detect and identify sensor and actuator faults by using analytical redundancy. An approach to further reconstruct sensor and actuator faults from the residual generated by the fault detection filter is proposed. The transfer matrix from the faults to the residual is derived in terms of the eigenvalues

NonLinear Fault Tolerant Flight Control for generic actuators fault models

2014 American Control Conference, 2014
This paper presents an Active Fault Tolerant Flight Control applied to an aircraft nonlinear longitudinal model in presence of simultaneous faults on both elevator and thrust actuators. The overall control system is based on a Fault Detection and Diagnosis module, designed by the NonLinear Geometric Approach, allowing fault isolation.

ROBUST FAULT-TOLERANT CONTROL ARCHITECTURE–ACTUATOR FAULT DETECTION AND RECONFIGURATION

Control and Intelligent Systems, 2010
Summary: Developing a fault-tolerant robust control architecture for a class of nonlinear, non-parameterizable, uncertain systems is investigated. Robust measures are developed to identify faculty actuators that would degrade the performance envelopes. These robust measures are in turn used to design a robust fault-tolerant control law which is capable

Fault-tolerant Compensation Control Incorporating Actuator Criticality

IFAC Proceedings Volumes, 2012
In this paper, actuator criticality analysis is integrated in the design of active fault-tolerant control systems. The main objective consists in the fault-tolerant controller synthesis which guarantees a highest overall system reliability while still maintaining immediate stability and tracking performance of reconfigured system. To achieve this task,
