Fault-tolerant actuators and drives—Structures, fault detection principles and applications

Annual Reviews in Control, 2009
Abstract As fault detection and fault diagnosis are more and more finding their way into modern industrial mechatronic products, it is now time to take the next step. Based on the research efforts for fault detection and diagnosis, a platform has been prepared for research on fault management, i.e.

Adaptive fault tolerant synchronization with unknown propagation delays and actuator faults

International Journal of Control, Automation and Systems, 2012
The paper addresses a practical issue in adaptive fault tolerant synchronization of masterslave systems with a constant signal propagation delay and actuator faults. First, a new concept of chaos synchronization is proposed, where the real value of the propagation delay can be estimated online by a proper adaptation mechanism; then, a novel adaptive ...

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 ...

Reconfigurable fault-tolerant UAV flight control against actuator faults

2016 Australian Control Conference (AuCC), 2016
In this study, the parameter identification based fault tolerant control of an unmanned aerial vehicle (UAV) dynamics is presented. When faults occur in the actuator, then the elements of the control distribution matrix (control derivatives) change. The Kalman filter (KF) is used in order to identify the control distribution matrix elements; thus, the ...
