Reliability Monitoring of Fault Tolerant Control Systems
This paper proposes a reliability monitoring scheme for active fault tolerant control systems using a stochastic modeling method. The reliability index is defined based on system dynamical responses and a safety region; the plant and controller are assumed to have a multiple regime model structure; and a semi-Markov model is built for reliability evaluation based on safety behavior of each regi...
متن کاملActuator Fault-Tolerant Control based on Set Separation
In this report an actuator fault-tolerant control (FTC) strategy based on set separation is presented. The proposed scheme employs a bank of observers which match the different fault situations that can occur in the plant. Each of these observers has an associated estimation error with a distinctive behaviour when a estimator matches the current fault situation of the plant. With this informati...
متن کاملSmart Reconfigurable Fault-Tolerant Flight Control against Actuator Failures
In this study, active fault tolerant flight control technique with actuation reconfiguration is proposed. For this purpose two-stage Kalman filter (TSKF) is designed to identify the control distribution matrix elements corresponding to the faulty actuator, and a control reconfiguration action is taken to keep the performance of the impaired aircraft same as that of the unimpaired aircraft. Thus...

متن کاملActuator Fault-tolerant Control Design Based on Reconfigurable Reference Input
The prospective work reported in this paper explores a new approach in order to enhance the performance of an Active Fault Tolerant Control System. This proposed technique is based on a modified recovery/trajectory control system which considered a reconfigurable reference input when performance degradation occurs on system due to faults in actuators dynamics. The added value of this work is to...
