This study introduces a strategy for robotic peg-hole assembly designed to efficiently transfer skills from a human instructor to a robot, achieved through a series of demonstrations and training sessions. Moving the peg fixed to the robotic arm’s end from the distal position to the top of the hole, which is represented as an autonomous dynamical system. During the modeling and generalization phas...Show More
Real-world tasks often require combinations of both discrete and rhythmic movements. However, most of current methods can only address one of them. This letter proposes a unified framework, Wavelet Movement Primitives (WMPs), which are built on Probabilistic Movement Primitives (ProMPs) integrated with Discrete Wavelet Transform (DWT), to model and learn both discrete and rhythmic trajectories fro...Show More
Helicopter systems present numerous benefits over fixed-wing aircraft in several fields of application. Developing control schemes for improving the tracking accuracy of such systems is crucial. This paper proposes a neural-network (NN)-based adaptive finite-time control for a two-degree-of-freedom helicopter system. In particular, a radial basis function NN is adopted to solve uncertainty in the ...Show More
An adaptive neural network (NN) control is proposed for an unknown two-degree of freedom (2-DOF) helicopter system with unknown backlash-like hysteresis and output constraint in this study. A radial basis function NN is adopted to estimate the unknown dynamics model of the helicopter, adaptive variables are employed to eliminate the effect of unknown backlash-like hysteresis present in the system,...Show More
In this paper, we propose an adaptive neural network-based fault-tolerant control for the two-degree of freedom (DOF) helicopter system with actuator fault and output constraints. First, the radial basis function neural network is used to estimate the uncertainty of the system. Moreover, adaptive auxiliary parameters are used to compensate the actuator failure. And then, the barrier Lyapunov funct...Show More
