A New Fault Tolerant Nonlinear Model Predictive Controller Incorporating an UKF-Based Centralized Measurement Fusion Scheme

A new Fault Tolerant Controller (FTC) has been presented in this research by integrating a Fault Detection and Diagnosis (FDD) mechanism in a nonlinear model predictive controller framework. The proposed FDD utilizes a Multi-Sensor Data Fusion (MSDF) methodology to enhance its reliability and estimation accuracy. An augmented state-vector model is developed to incorporate the occurred senso...

Redundancy Analysis and a Distributed Self-Organization Protocol for Fault-Tolerant Wireless Sensor Networks

Sensor nodes in a distributed sensor network can fail due to a variety of reasons, e.g., harsh environmental conditions, sabotage, battery failure, and component wear-out. Since many wireless sensor networks are intended to operate in an unattended manner after deployment, failing nodes cannot be replaced or repaired during field operation. Therefore, by designing the network to be fault-tolera...

Robust Sensor Fault-Tolerant Control Scheme for Wind Turbines with Hydrostatic Transmission

In this paper, an observer bank design for sensor fault diagnosis and fault-tolerant control schemes for wind turbines with hydrostatic transmissions are presented. The sensor faults are detected and isolated by several observers using different sensor signals. Starting from a detailed problem formulation that takes into account structured model uncertainties and external inputs, the sufficient...

Fault Diagnosis and Fault-tolerant Control of Position Sensors for Switched Reluctance Motors

Position sensor is the key of exact commutation for switched reluctance motor (SRM). When position sensor is faulted, some phase information of commutation will be lost, causes torque decrease, affects the system reliability. Through the analysis of the fault position signals, a real-time diagnostic method that detected the edge sequences of position signals and calculated the angle between the...
