Experiments on Fault-Tolerant Active Vibration Control

Journal of Dynamic Systems, Measurement, and Control, 2008
The purpose of this work is to experimentally demonstrate a fault-tolerant active vibration control system. Active vibration control is achieved using piezoceramic sensors and actuators (transducers) that are attached to a simply supported beam. These transducers are used by a set of optimal H2 feedback compensators to minimize the lateral vibration of

Output Feedback Active Fault Tolerant Control for a 3-DOF Laboratory Helicopter With Sensor Fault

IEEE Transactions on Automation Science and Engineering
In this paper, an output feedback-based active fault tolerant control (FTC) scheme is proposed for an unstable three degree-of-freedom (3-DOF) helicopter equipped only with angular position sensors, of which a single sensor can be faulty.

Active fault tolerant control with actuation reconfiguration

IEEE Transactions on Aerospace and Electronic Systems, 2004
This paper presents an integrated approach to fault detection, isolation, and fault tolerant control (FTC). In the proposed approach a constrained Kalman filter based fault detection and isolation (FDI) method (Larson et al., 2002) is modified to reduce its computation load and then applied to detect and isolate a faulty actuator or sensor.

Adaptive fault tolerant control for active suspension

2016 IEEE First International Conference on Control, Measurement and Instrumentation (CMI), 2016
This paper deals an adaptive fault tolerant control for active suspension in the presence of actuator saturation. An adaptive state-feedback controller is designed to tackle the issue of actuator fault. A Disturbance observer is utilized to observe the lumped disturbance.

Active Fault-Tolerant Control for Stochastic Fully Actuated Systems With Local Faults

IEEE Transactions on Industrial Informatics
This article portrays a class of local faults (LFs), whose basic characteristic is that the fault occurs only when the system state is in a certain domain.

Two-level Active Fault Tolerant Control approach

Eighth International Multi-Conference on Systems, Signals & Devices, 2011
In this paper, a two-level reconfiguration action is used to design an Active Fault Tolerant Control (AFTC) system. The first level of the procedure is triggered when the impact of the fault on the system performance is limited. The reconfigurable controller is updated by the new post-fault system model.

Semi-active fault-tolerant control of whole-spacecraft vibration isolation platform based on human-simulated intelligent controller

Smart materials and structures (Print)
Satellites are suffered from a series of external loads transmitted from the satellites-rocket interface during the launch phase. The satellite can be caused to experience broadband vibration by those loads.

Fault tolerant control of active magnetic bearings

IEEE International Symposium on Industrial Electronics. Proceedings. ISIE'98 (Cat. No.98TH8357), 2002
A nonlinear model of a Rolls-Royce turbomachine's rotor supported by active magnetic bearings (AMBs) is presented. The model has the capability to model magnetic bearing systems of a variety of different configurations. A multiobjective genetic algorithm (MOGA) is used to design PID controllers for the AMB system with five different bearing ...

Active Fault-Tolerant Control With Adaptive Estimation Error Compensation for Nonlinear Systems: Achieving Asymptotic Tracking

IEEE Transactions on Industrial Informatics
For active fault-tolerant control (AFTC) of nonlinear systems, inaccurate fault estimation caused by mismatched disturbances can result in compensation errors in the fault-tolerant controllers, making it difficult to achieve asymptotic tracking.
