Antidisturbance control issue for singular Markovian jump systems under infinitely
unobservable states and multiple disturbances is investigated. One of the disturbances is …

In this article, a novel unknown input interval observer (UIIO) is proposed for systems not
satisfying the relative degree condition. In interval estimation, estimation errors are required …

Partial state estimation has numerous applications in practice. Nevertheless, designing
delay-dependent functional observers (FOs) for systems with unknown time delays is …

In existing work of sliding mode observers (SMOs) for descriptor systems, a necessary
condition is that the system must be infinitely observable. This paper presents a scheme that …

This paper presents the design of a sliding-mode perturbation observer-based sliding-mode
control for stability enhancement of multi-machine power systems. The combinatorial effect …

The fault‐tolerant control and vibration suppression for flexible spacecraft without angular
velocity measurement are investigated. External disturbances, actuator faults, unknown …

Two state/fault estimation methods using terminal sliding mode (TSM) concepts are
presented in this paper. In contrast with conventional sliding modes, which guarantee …

This paper presents a novel common functional observer scheme for three systems with
unknown inputs. The scheme uses three observers in cascade with two logic switches. The …

This paper presents an observer scheme for state and unknown input estimation for a class
of infinitely unobservable descriptor systems. Though there are observer schemes for …

Designing delay‐dependent functional observers for LTI systems with multiple known time‐
varying state delays and unknown time‐varying input delays is studied. The input delays are …
