Evaluation of a fault-tolerant control design for actuator faults

Proceedings of the 36th IEEE Conference on Decision and Control, 2002
Fault-tolerant control or reconfigurable control systems are generally based on a nominal control law associated to a fault detection and isolation module. A general review of techniques dealing with this problem is given and a new fault-tolerant control approach is described.

Actuator Fault Detection for Vehicle Lateral Dynamics

2018 5th International Conference on Control, Decision and Information Technologies (CoDIT), 2018
This paper proposes an actuator fault detection based on unknown input observer for simultaneously state estimation and fault estimation applied to lateral vehicle dynamics. The lateral dynamics is modeled by a linear parameter varying model where the longitudinal velocity is considered as parameter varying.

Fault-tolerant control method for actuator and component faults

Proceedings of the 37th IEEE Conference on Decision and Control (Cat. No.98CH36171), 2002
In this paper, a fault-tolerant control method is developed. This method makes possible the compensation of additive or multiplicative actuator and component faults. Its principle is based on the online estimation of a quantity which is equal to zero in the fault-free case and equal to the fault magnitude when a fault occurs on the system.

Robust Estimation of Actuator Faults

2016
We have discussed the issue of actuator/sensor fault detection and isolation (FDI) in the last two chapters. However, FDI can only indicate when and where a fault occurs in the system, but cannot provide more comprehensive information of the fault such as magnitude, shape, and duration.

Detection and Isolation of Actuator Faults

2016
This chapter presents an SMO-based actuator FDI approach for uncertain Lipschitz nonlinear systems. It is assumed in this chapter only actuator faults occur in the system.

Actuator Fault Detection in UAVs

2014
Future unmanned aerial vehicles (UAVs) will be designed to achieve their missions with increased efficiency, safety, and security. To this end, an efficient fault detection and isolation (FDI) system should be capable of monitoring the health status of the aircraft.

Fault diagnosis of electrical actuators

2011
Actuators usually transform low-powered manipulated variables (e.g. analog voltages 0––10V, applied DC currents 0––20mA or 4––20 mA, pneumatic pressures 0:2 – –1 bar, or hydraulic pressures 0 – –150 bar) into process input variables of a much higher power level.

Fault diagnosis of fluidic actuators

2011
Fluidic actuators are characterized by their rugged design and high power-to-weight ratio. They enable one to generate linear motions easily and directly by employing hydraulic cylinders and diaphragm drives. They also dissipate energy only if in dynamic operation and during holding phases generate high reaction forces with little energy consumption ...
