Disturbance observer (DOB) has been one of the most widely used robust control tools since
it was proposed by Ohnishi in 1983. This paper introduces the origins of DOB and presents …

A new disturbance observer-based control method is presented in this paper to address the
attitude tracking problem of rigid-body spacecraft in the presence of external disturbances …

This article presents a control scheme for stabilizing a vibrating flexible hose used for aerial
refueling subject to bounded actuators for the rate and magnitude. A dynamical model of …

The distributed formation tracking control problem with multiple leaders under actuator faults
and constraints is investigated in this article. All followers in the multiagent system should …

This paper investigates the attitude tracking problem for the flexible spacecraft composed of
a rigid platform with a rotating appendage. Two robust attitude controllers, each matched to …

This article presents a prescribed performance adaptive control scheme for the attitude
tracking and vibration reduction of flexible spacecraft modeled by partial differential …

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

A novel finite-time neural control strategy is proposed for flexible spacecraft with guaranteed
attitude tracking performance subject to parametric uncertainty, uncertain external …

To realize high-precision attitude stabilization of a flexible spacecraft in the presence of
complex disturbances and measurement noises, an iterative learning disturbance observer …

In this paper, we study a boundary vibration control problem for a flexible aircraft wing
system with input signal quantization and unknown input disturbances. The wing system is a …
