Smart Actuator Fault Diagnosis

IFAC Proceedings Volumes, 2000
Abstract The emergence of low-cost microelectronics promotes the integration of different technologies to produce a local autonomous element, such as 'smart' sensors and actuators. Various requirements are needed so as to achieve smartness. One of the most important issues is the integration of self-diagnosis. For the implementation of self-diagnosis,

Fault-tolerance Evaluation of Actuator Fault Configurations

2010
In this chapter, the fault tolerance of a certain actuator fault configuration (AFC) is evaluated within the framework of a linear MPC law with constraints. The issue of fault-tolerance evaluation has already been treated in the literature for an LQR problem without constraints (Staroswiecki, 2003), due to the existence of an analytical solution ...

ROBUST FAULT-TOLERANT CONTROL ARCHITECTURE–ACTUATOR FAULT DETECTION AND RECONFIGURATION

Control and Intelligent Systems, 2010
Summary: Developing a fault-tolerant robust control architecture for a class of nonlinear, non-parameterizable, uncertain systems is investigated. Robust measures are developed to identify faculty actuators that would degrade the performance envelopes. These robust measures are in turn used to design a robust fault-tolerant control law which is capable

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.

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.

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.
