Fault Estimation Method for Nonlinear Systems With Perturbations Based on Augmented Fault Observer
IEEE AccessThis paper proposes a robust fault estimation method for nonlinear systems with both actuator and sensor faults. Specifically, a singular system is constructed by combining the state vector of the system with the fault vector of the sensor, and an ...

Distribution systems fault analysis considering fault resistance estimation
International Journal of Electrical Power & Energy Systems, 2011 Abstract Fault resistance is a critical component of electric power systems operation due to its stochastic nature. If not considered, this parameter may interfere in fault analysis studies. This paper presents an iterative fault analysis algorithm for unbalanced three-phase distribution systems that considers a fault resistance estimate.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Parents of children treated for acute lymphoblastic leukemia (ALL) often experience significant caregiver burden and disruption to their well‐being. While parent quality of life (QoL) during treatment is well characterized, little is known about outcomes during early survivorship.

Fault tolerant control in an unmanned bicycle robot via sliding mode theory
IET Cyber-systems and Robotics, 2022 In this work, a new active fault tolerant control (FTC) is developed for an unmanned bicycle robot based on an integration between a sliding mode control (SMC), fault detection (FD), and fault estimation (FE) via a residual signal.

Framework for state and unknown input estimation of linear time-varying systems
, 2016 The design of unknown-input decoupled observers and filters requires the assumption of an existence condition in the literature. This paper addresses an unknown input filtering problem where the existence condition is not satisfied.
