چکیده
In this paper, a fixed-time adaptive neural control scheme is proposed to solve the prescribed tracking problem of robot manipulators in presence uncertain dynamics, and stuck-type actuator failures which are unknown time, pattern, values. Technically, combination networks used handle uncertainties system an compensation mechanism designed accommodate occurring actuators, also systematic design procedure based on performance bounds presented establish conditional inequality for ensuring stability. With our scheme, it can be proved rigorously that errors joint space always kept within bounds, converge small region zero bounded settling addition closed-loop signal boundedness. The validated through simulations.

*Correspondence: [email protected] College of Mathematics and Systems Science, Shandong University of Science and Technology, Qingdao, Shandong 266510, P.R. China Abstract We consider adaptive compensation for infinite number of actuator failures in the tracking control of uncertain nonlinear systems. We construct an adaptive controller by combining the common Lyapunov function approach and the...
متن کاملAdaptive RBF network control for robot manipulators
TThe uncertainty estimation and compensation are challenging problems for the robust control of robot manipulators which are complex systems. This paper presents a novel decentralized model-free robust controller for electrically driven robot manipulators. As a novelty, the proposed controller employs a simple Gaussian Radial-Basis-Function Network as an uncertainty estimator. The proposed netw...
متن کاملAdaptive synchronised tracking control for multiple robotic manipulators with uncertain kinematics and dynamics
In this study, a new adaptive synchronized tracking control approach is developed for the operation of multiple robotic manipulators in the presence of uncertain kinematics and dynamics. In terms of the system synchronization and adaptive control, the proposed approach can stabilize position tracking of each robotic manipulator while coordinating its motion with the other robotic manipulators. ...

In [18], a class of nonlinear systems with stochastic actuator failures have been studied. Stochastic functions related to Markovian variables have been introduced to describe the failure scaling factors for each actuators. In this paper we consider the kind of systems involving state-delay, which is much more practical, and adaptive fault-tolerant control problem has been studied. Two main cha...
