Wind turbines play an increasingly important role in renewable power generation. To ensure
the efficient production and financial viability of wind power, it is crucial to maintain wind …

This survey of model-based fault diagnosis focuses on those methods that are applicable to
aerospace systems. To highlight the characteristics of aerospace models, generic non-linear …

This paper considers fault detection and estimation issues for a class of nonlinear systems
with uncertainty, using an equivalent output error injection approach. A particular design of …

Wind turbine pitch systems are essential for actuating desired blade angles and hence to
keep the generator at rated speed in operation region 3. In the presence of parametric pitch …

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 …

This paper presents an observer-based fault reconstruction method for PEM fuel cells. This
method extends the results of a class of nonlinear uncertain systems with Lipschitz …

Design procedures are proposed for two different classes of observers for systems with
unknown inputs. In the first approach, the state of the observed system is decomposed into …

This paper studies the fault estimation problem for a class of nonlinear semi‐Markovian
jump systems with partly unknown transition rates and output quantization. Firstly, a mode …

In this article, an actuator fault detection and isolation scheme for a class of nonlinear
systems with uncertainty is considered. The uncertainty is allowed to have a nonlinear …

In this paper, a class of nonlinear systems with uncertain parameters is considered. A novel
adaptive law is designed to identify unknown parameters under the assumption that the time …
