This article develops an adaptive neural-network (NN) boundary control scheme for a
flexible manipulator subject to input constraints, model uncertainties, and external …

We propose an adaptive neural-network-based fault-tolerant control scheme for a flexible
string considering the input constraint, actuator gain fault, and external disturbances. First …

The flexible manipulator servo system considering the second-order modal and two-
dimensional deformation is too complicated, which is not conducive to real-time control. In …

A variable-length dual-flexible servo system is a complex nonlinear system that consists of a
servo motor, a flexible joint, and a variable-length flexible load. In order to describe the …

This study focuses on an adaptive fault-tolerant boundary control (BC) for a flexible string
(FS) in the presence of unknown external disturbances, dead zone, and actuator fault. To …

A fuzzy adaptive event-triggered finite-time constraint control for the uncertain nonlinear
system with input hysteresis is developed. Input hysteresis, uncertain and nonlinear …

In this study, we propose an adaptive fuzzy event-triggered control scheme for an
autonomous aerial refueling hose system involving uncertainty, an event-triggered …

Abstract Space flexible robotic arms can be installed on space stations or spacecraft to
perform on-orbit tasks such as capturing artificial satellites, removing space debris, and …

Gravity and flexibility will cause fluctuations of the rotation angle in the servo system for
flexible manipulators. The fluctuation will seriously affect the motion accuracy of end …

In this paper, a fixed-time control method is proposed for an uncertain robotic system with
actuator saturation and constraints that occur a period of time after the system operation. A …
