Event-Triggered Prescribed-Time Fuzzy Control for Space Teleoperation Systems Subject to Multiple Constraints and Uncertainties
TL;DR: This article shows that, with the proposed controller, the synchronization tracking errors are guaranteed to converge to a user-defined residual set within preassigned settling time, and never exceed the prescribed range despite unknown control direction and actuator faults, which solves the long-standing constraint issue with more flexibility.
Journal ArticleDOI
Coordinated stabilization for space robot after capturing a noncooperative target with large inertia
TL;DR: In this article, a coordinated stabilization scenario is introduced to reduce the angular momentum, which has two stages, Momentum Reduction and Momentum Redistribution, for a non-cooperative target with large inertia grasped by a space robot.
Journal ArticleDOI
Adaptive finite‐time control for bilateral teleoperation systems with jittering time delays
Journal ArticleDOI
Modeling and simulation of point contact multibody system dynamics based on the 2D LuGre friction model
TL;DR: In this paper, a modeling method and algorithm for point contact non-smooth multibody system based on the 2D LuGre friction model is presented, and the effectivity of the parameter identification method is verified by a numerical simulating example.
Journal ArticleDOI
Manipulability measure of dual-arm space robot and its application to design an optimal configuration
TL;DR: Simulation results show that the proposed manipulability measure is useful for a multi-arm space robot and optimal configuration can be extended and applied to the coordinated soft rendezvous and docking and the target capture in the field of on-orbit servicing.
