Space exploration and exploitation depend on the development of on-orbit robotic
capabilities for tasks such as servicing of satellites, removing of orbital debris, or …

Permanent magnet synchronous motors (PMSMs) are known as highly efficient motors and
are slowly replacing induction motors in diverse industries. PMSM systems are nonlinear …

This paper develops a novel control methodology for tracking control of robot manipulators
based on a novel adaptive backstepping nonsingular fast terminal sliding mode control …

The requirements for the control performances of space manipulators, especially for the
stability and accuracy of the attitude control systems of the base spacecrafts, are ever …

Sliding mode control (SMC) is attractive for nonlinear systems due to its invariance for both
parametric and nonparametric uncertainties. However, the invariance of SMC is not …

This article investigates the predefined time trajectory tracking control of uncertain nonlinear
robotic systems. A radial basis function neural network (RBFNN) is used to estimate …

This paper investigates a difficult problem of tracking control for robotic manipulations with
guaranteed high accuracy. Uncertain kinematics, unknown torques including unknown …

This paper addresses a long-standing yet well documented open problem on task-space
trajectory tracking control of robotic manipulators subject to both uncertain dynamics and …

This paper deals with the design of a robust hierarchical multiloop control scheme to solve
motion control problems for robot manipulators. The key elements of the proposed control …

This paper addresses the problem of robust trajectory tracking for uncertain robot
manipulators within a priori fixed-time. A new sliding surface is first proposed and a robust …
