Controllability Analysis and Degraded Control for a Class of Hexacopters Subject to Rotor Failures [PDF]
This paper considers the controllability analysis and fault tolerant control problem for a class of hexacopters. It is shown that the considered hexacopter is uncontrollable when one rotor fails, even though the hexacopter is over-actuated and its ...

Control Approach to Fault Disambiguation
To ensure resilience, systems must be endowed with capabilities for rapid detection, response, and recovery to disruptiveevents. In this paper we focus on faults as disruptive events and use a diagnosis engine for their detection and isolation. In particular we use model-based diagnosis, where the diagnosis engine is provided with a model of the system,

Fault estimation and fault-tolerant control for discrete-time dynamic systems [PDF]
In this paper, a novel discrete-time estimator is proposed, which is employed for simultaneous estimation of system states, and actuator/sensor faults in a discrete-time dynamic system.

CONTROLLERS FOR FAULT TOLERANT ACTUATORS
The Fly‐by‐Wire technology enables flexible shaping of both effective dynamics and handling qualities of aircraft. This solution extends aircraft possibilities and supports the pilot by use of high‐level control laws. Application of FBW for aircraft would make flying both safer, and more popular. On the other hand the FBW system must be highly reliable.

Fault diagnosis and fault‐tolerant control in aerospace systems [PDF]
Modern technological and safety‐critical systems rely on sophisticated control solutions to meet increased performance demands in faulty conditions and in terms of reliability and safety requirements. A conventional feedback control design for a complex system may give unsatisfactory performance or even instability, in the event of malfunctions in ...

Estimation of inertia demand in power systems considering wind power virtual inertia
The high proportion of renewable energy integrated into the grid through numerous power electronic devices has reduced the overall system inertia level and operational stability and caused poor disturbance resistance.

Fault-Tolerant Control of Linear Quantum Stochastic Systems
In quantum engineering, faults may occur in a quantum control system, which will cause the quantum control system unstable or deteriorate other relevant performance of the system.
