Active versus passive fault tolerant control of a High Redundancy Actuator

2009 European Control Conference (ECC), 2009
The High Redundancy Actuator (HRA project investigates the use of large numbers of small actuation elements to achieve fault tolerance. The large number of components involved poses a unique challenge from a control perspective. This paper presents the two main options to control the HRA: using robust control (passive fault tolerance), and ...

Passive/active fault tolerant control for LTI systems with actuator outages

2009 European Control Conference (ECC), 2009
Many fault tolerant control applications consider a set of faults that is known in advance. Passive and active fault tolerance schemes aim at guaranteeing stability and performances for the whole set, differing by the level of simplicity and performance they allow.

Passive supervisor for railway fault-tolerant Ethernet networked control systems

ETFA2011, 2011
In this study, OPNET simulations are run to study the performance of a single Gigabit Ethernet two-wagon train control network. The network carries both control and entertainment loads. Each wagon has two servers; a Controller to carry the control load and an Entertainment Server to carry the entertainment load.

Passive Fault Tolerance for a Magnetic Bearing Under PID Control

Volume 4: Manufacturing Materials and Metallurgy; Ceramics; Structures and Dynamics; Controls, Diagnostics and Instrumentation; Education; IGTI Scholar Award, 2001
NASA Glenn Research Center (GRC) has developed a Fault-Tolerant Magnetic Bearing Suspension rig to enhance the safety of the bearing system for multiple component failures. A simple proportional-integral-derivative (PID) controller with no fault detection mechanisms was tested in a passive way where the initial bias current and control gains for all ...

Passive fault tolerant control design of energy management system for electric vehicle

2014 IEEE 23rd International Symposium on Industrial Electronics (ISIE), 2014
In this paper, we present a passive fault tolerant control energy management for two-converters parallel configuration in electrical vehicle system. The passive FTC is based on H-infinity approach (H-infinity full order and fixed H-infinity structure); this PFTC is coupled with the optimal control to optimize the consumption of the FC fuel.

Fault-tolerant PID controllers using a passive robust fault diagnosis approach

Control Engineering Practice, 2000
Abstract Automatic controlled systems are susceptible to faults. Faults can be amplified by closed loop control systems, and they can cause a malfunction of the loop. The closed loop may alternatively hide a fault from being observed until the plant eventually reaches a state in which loop failure is inevitable.

An active and passive combined fault-tolerant control approach for UAV with the control surface fault

Transactions of the Institute of Measurement and Control
In this paper, the fault-tolerant control (FTC) problem of fixed-wing unmanned aerial vehicle (UAV) with control surface structural damage is studied. An active-passive combined FTC algorithm based on sliding mode and adaptive control is proposed. Considering that the UAV is required to be instantaneously stable in the initial stage of the fault, a one-
