This work proposes a proportional-integral fault estimation observer for nonlinear systems
by means of convex structures. Unlike the traditional approaches that consider quadratic …

This paper proposes the design of a robust Takagi–Sugeno (T–S) fuzzy reconfiguration
block for systems with unmeasured premise variables. The reconfiguration block is …

This paper presents actuator fault detection of discrete‐time nonlinear descriptor systems by
means of nonlinear unknown input observers. The approach is based on the exact …

This article addresses the problem of state and unknown inputs (UIs) estimation for
nonlinear systems with arbitrary relative degree with respect to the UIs. For this purpose, a …

This paper introduces a technique for simultaneous estimation of additive and multiplicative
faults in the actuators of nonlinear systems represented by quasi‐linear parameter varying …

Robust stabilization of a class of uncertain nonlinear systems through a sampled‐data
control law is considered in this work. Based on the forward discrete‐time Euler …

In this paper, an observer with exponential time-varying gain is proposed for a class of
nonlinear systems in Takagi–Sugeno form with both continuous-time and aperiodic sampled …

This paper is concerned with fault reconstruction based on sliding mode observers; its
contribution is twofold: on the one hand, it develops a novel sliding mode observer whose …

The number of people affected by motor impairment has increased considerably in recent
years, raising, in consequence, the interest in the use of assistive robotic devices for …

This report establishes that overcoming limitations on standard synthesis of sliding mode
observers, namely, the rank and size requisites for output/perturbation decoupling and the …
