Fault Tolerant Control for an Over-Actuated WAM-V Catamaran

Fault-tolerant control design for over-actuated system conditioned by reliability: a drinking water network application

An optimal control law synthesis conditioned by the reliability of actuators in the presence of failures is presented in this paper. The aim is to preserve the health of the actuators and the availability of overactuatued system both in the nominal situation and in the presence of some actuator failures. The reliability assessment is computed by Bayesian Network since it is well suited to model...

Fault-Tolerant Control of a Nonlinear Process with Input Constraints

A Fault-Tolerant Control (FTC) methodology has been presented for nonlinear processes being imposed by control input constraints. The proposed methodology uses a combination of Feedback Linearization and Model Predictive Control (FLMPC) schemes. The resulting constraints in the transformed process will be dependent on the actual evolving states, making their incorporation in the de...

Fault Tolerant Feedback Control

An architecture for fault tolerant feedback controllers based on the Youla parameterization is suggested. It is shown that the Youla parameterization will give a residual vector directly in connection with the fault diagnosis part of the fault tolerant feedback controller. It turns out that there is a separation between the feedback controller and the fault tolerant part. The closed loop feedba...

Robust Fault-Tolerant Control

Design of an Active Approach for Detection, Estimation and Short-Circuit Stator Fault Tolerant Control in Induction Motors

Three phase induction motors have many applications in industries. Consequently, detecting and estimating the fault and compensate it in a way that the faulty induction motor satisfies the predefined goals are important issues. One of the most common faults in induction motors is the short circuit of the stator winding. In this paper, an active fault-tolerant control system is designed and pres...
