This article deals with the problem of finite-time state estimation for a class of non-linear
systems possibly affected by modelling uncertainties and/or unknown inputs. The proposed …

Unknown input observers (UIOs) are observers that have stable error dynamics that are
independent of unknown inputs. This paper studies such observers for non-linear systems …

The disturbance rejection control problem is studied in this article for the 2-D Roesser
system within 2-D event-triggered control frameworks. First, the unknown disturbance is …

A class of nonlinear uncertain mechanical systems with the Coriolis term, is considered.
Since these systems generally do not satisfy the bounded-input-bounded-state property, a …

This paper presents a finite time unknown input observer for linear systems, ie an observer
which estimates the exact state of a linear system with unknown input disturbances in a …

This paper proposes a global sliding mode observer for a class of nonlinear mechanical
systems with two degrees of freedom. For the observer design, besides the usual Coriolis …

Observation issues are of fundamental importance for reaction systems due to the limited
availability of on-line sensors and the uncertainties related to the mathematical model. The …

Symbolic control is an approach to the control of continuous or hybrid systems with
specifications expressed in a logic form. This approach is based on the use of symbolic …

This paper studies the problem of designing interval observers for a family of discrete‐time
nonlinear systems subject to parametric uncertainties and external disturbances. The design …

In this paper a family of homogeneity–based observers is proposed to estimate the state of a
class of multiple–outputs linear systems with some parametric uncertainties and unknown …
