Active Fault Tolerant Control Based on a Novel Tracking Differentiator for Elevating Stage Control System

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...

Sensor Fault Tolerant Control for AUVs Based on Replace Control

To improve the reliability of the motion control system for an autonomous underwater vehicle (AUV), sensor fault tolerant control based on replace control was talked about. This paper analyzed the decoupling controller and the sensor system firstly, and proposed a fault tolerant control strategy based on the ideas of replacing the fault sensor outputs by the sliding-mode observer outputs (also ...

Fault Tolerant Control for an Electric 4WD Vehicle's Path Tracking with Active Fault Diagnosis

This paper investigates the path tracking problem for an electric vehicle which has four electromechanical wheel systems under normal and faulty conditions. With considering wheel slip constraints and certain actuator faults, a passive fault-tolerant controller based on variable structure control is developed to maintain the system stability and guarantee the acceptable tracking performance. Th...

Fault-Tolerant Control for LPV systems based on Fault Compensator

This paper proposes a fault-tolerant control (FTC) scheme for polytopic linear parameter varying (LPV) systems. We first propose a fault compensator whose structure is simple, but effective against actuator faults. Then, in order to show its basic idea, we consider a state feedback FTC scheme based on the fault compensator. Next, the FTC algorithm is extended to output feedback FTC scheme. The ...
