Locomotion of Linear Actuator Robots Through Kinematic Planning and Nonlinear Optimization
IEEE Transactions on robotics, 2020 In this article consider a class of robotic systems composed of high-elongation linear actuators connected at universal joints. We derive the differential kinematics of such robots, and show that any instantaneous velocity of the nodes can be achieved ...

DNN identification and fault-tolerant control for non-linear systems with unknown faults
The Journal of Engineering, 2019 In this study, dynamical neural networks (DNNs) are used as an online identifier for a class of non-linear systems with unknown actuator faults. By integrating the designed non-linear FD observer with adaptive regulation algorithm, the parameter coupling

A novel stick-slip based linear actuator using bi-directional motion of micropositioner
Mechanical systems and signal processing, 2019 A stick-slip based linear actuator was proposed in this paper, which applied the axial motion of the micropositioner to adjust the preload, and the lateral motion to drive the slider.
