Fault-tolerant control of three-pole active magnetic bearing
Expert Systems with Applications, 2009Active magnetic bearings have many advantages over conventional bearings due to contactless operation and adjustable force dynamics. However, one of the obstacles associated with these bearings is failure modes, which may result in destructive rotor dynamic behaviour.

Fault estimation and active fault tolerant control for servo systems
2016 IEEE International Conference on Real-time Computing and Robotics (RCAR), 2016In this paper, the problems of fault estimation and fault tolerant control for motor servo systems are investigated. The motor servo systems are modeled as continuous-time linear systems with unknown inputs and actuator faults. Based on the faulty system model, a robust fault estimation and active fault tolerant control scheme is proposed.

On active fault tolerant control for a class of time-delay system
IFAC Proceedings Volumes, 2009Abstract This paper deals with the problem of active fault tolerant control for a class of linear time-delay systems. A new H∞ controller in generalized internal model architecture and an adaptive observer-based fault estimator are proposed for the active fault tolerant control system.

Intelligent active fault tolerant control system and flight safety
2013 IEEE 7th International Conference on Intelligent Data Acquisition and Advanced Computing Systems (IDAACS), 2013In this paper, reconfigurable (active) flight control system for recovering controllability of the aircraft when an unexpected problem (such as faults or failures to the actuators/sensors or structural damage) occurs during a flight is proposed.

On active fault-tolerant control in behavioral context
2012In this note, we present a model-free approach to solve an active fault-tolerant control problem for linear time-invariant systems using the mathematical framework of behavioral theory. In our control structure, we do not require an explicit fault diagnosis module to identify the complete fault information.
