Multi-objective Optimization of a Composite Material Propeller Structure

Hangkong gongcheng jinzhan, 2018
Reducing the weight and increasing the torsion stiffness are the two main pursuits in the engineering design work of propeller blade structure. And the application of composite materials has improved the designability of propeller structure.

PID‐Like Robust Control of Non‐Minimum Phase Robotic Manipulators

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This paper proposes an output‐feedback tracking controller for non‐minimum phase nonlinear systems with unknown uncertainties and external disturbances, where not all states are measurable, and the zero dynamics are unstable. The approach combines a backstepping‐based stabilizing state‐feedback law with a cascade extended high‐gain observer ...

Neural Network‐Based Adaptive Super‐Twisting Control for Perturbed Nonlinear Systems: Lyapunov Design

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT A newly developed robust control strategy based on an adaptive neural network (ANN) estimator performed in concert with adaptive super‐twisting (ASTW) control is presented. The proposed adaptive robust control algorithm is applied to a class of perturbed nonlinear systems and features a significantly decreased control gain with respect to the ...

M2M technologies for UAV-to-UAV communication

, 2021
Drones have gained huge popularity in the recent years, and with the huge increase in usage and demand has brought open a new Ad-Hoc network specifically made for drones. The existing Ad-Hoc networks, MANET and VANET, was shown to be unsuitable for flying drones as the current Ad-Hoc network were not fitted for 3D spaces and whereas only focused on the

Mapping River Bed Topography in Whitewater Rapids Using Bathymetric LiDAR

River Research and Applications, EarlyView.
ABSTRACT Bathymetric LiDAR captures river topography efficiently for clear and shallow water, but for mountain rivers, whitewater rapids still pose challenges. This study proposes a novel method to enable the extraction of bottom returns specifically in turbulent whitewater sections.
