This article highlights the interest of step-by-step higher order sliding mode observers for
Multi-Input Multi-Output (MIMO) nonlinear systems with unknown inputs. A structural …

This paper proposes an active fault-tolerant control (AFTC) system for spacecrafts subject to
model uncertainty, external disturbance and actuator fault simultaneously. Fault diagnosis is …

This paper considers the problems of control performance degradation caused by the
vibration of flexible accessories and external disturbance during the attitude maneuvering …

In this paper, a new fuzzy adaptive control approach is developed for a class of SISO strict-
feedback nonlinear systems, in which the nonlinear functions are unknown and the states …

This work deals with nonlinear observer synthesis for a particular class of hybrid dynamic
systems (HDS): autonomous switching systems with jumps. The jumps can result from the …

The main topic of this paper is the problem of constructing observers for switched
mechanical systems, which includes, as a specific case, the design of observers based on …

This article is concerned with the design of impulsive observers with variable update
intervals for Lipschitz nonlinear systems with delays in state. Discontinuous Lyapunov …

Robust state estimation and fault diagnosis are challenging problems in the research of
hybrid systems. In this paper, a novel robust hybrid observer is proposed for a class of …

This paper addresses the state observation and unknown input estimation of a class of
switched linear systems with unknown inputs. This class of systems may have modes in …

This paper deals with the synthesis of high gain observers for uniformly observable
nonlinear hybrid systems. First, the single output-case is treated and then an extension is …
