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 …

In this paper, the problem of design of interval observers for Linear Parameter-Varying (LPV)
systems, containing non-detectable or non-strongly-observable parts, is addressed. Firstly, a …

This paper is concerned with state estimation for continuous-time nonlinear systems. By
means of a polytopic exact representation of the system using interpolation functions whose …

Sliding-mode-based differentiation of the input f (t) yields exact estimations of the derivatives
f ̇,…, f (n), provided an upper bound L (t) of| f (n+ 1)(t)| is available in real-time. In practice it …

Abstract The Describing Function approach is used to adjust the parameters of fast-
oscillations (chattering) caused by the presence of fast-actuators in Super-Twisting control …

This paper provides an extension of the observability rank condition to nonlinear systems
driven by both known and unknown inputs. In particular, the systems here considered are …

Controlling chaotic systems is very often investigated by using empirical laws, without taking
advantage of the structure of the governing equations. There are two concepts, observability …

This paper studies the problem of observer based fast nonsingular terminal sliding mode
control schemes for nonlinear non-affine systems with actuator faults, unknown states, and …

Observability is a fundamental structural property of any dynamic system and describes the
possibility of reconstructing the state that characterizes the system from fusing the …

New finite-time-exact robust (FTER) differentiators, filters and observers based on sliding
modes are produced which are capable of filtering out unbounded sampling noises and of …
