Integrated Fault Estimation and Fault-Tolerant Control for Dynamic Positioning of Ships

Integrated Fault-Detection and Fault-Tolerant Control of Process Systems

The problem of implementing fault-tolerant control to nonlinear processes with input constraints subject to control actuator failures is considered, and an approach predicated upon the idea of integrating fault-detection, feedback and supervisory control is presented and demonstrated. To illustrate the main idea behind the proposed approach, availability of measurements of all the process state...

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...

Fault Tolerant Control in Dynamic Systems

Abstract: In this paper a method for fault tolerant control in dynamic systems is presented. In an integrated design, the proposed approach is composed of two stages. The first step is the detection and isolation of the failed component while the second step is represented by the reconfiguration mechanism. It consists in the estimation of new control parameters after evaluation of the performan...

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...
