An Integrated Numerical and Bollard Pull Evaluation Approach for Early‐Stage Resistance and Thrust Assessment of a Small Craft

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Early‐stage hydrodynamic assessment of slender multihull vessels is challenged by limited geometric maturity, uncertain propulsion integration, and strong sensitivity to operating conditions. Under such constraints, reliance on a single analytical or numerical method may lead to misleading design decisions due to oversimplification or ...

On Stability of Open‐Loop Operation without Rotor Information for Brushless DC Motors [PDF]

Mathematical Problems in Engineering, 2014
Open‐loop operation mode is often used to control the Brushless DC Motors (BLDCMs) without rotor position sensors when the back electromotive force (EMF) is too weak due to the very low rotor velocity. The rotor position information is not necessary in this mode and the stator windings are supplied with voltages under a certain ratio of the amplitude ...

Linear System Identification and Control of a Low‐Cost High‐Performance Omnidirectional Marine Surface Vehicle for Swarming Applications

Journal of Field Robotics, EarlyView.
ABSTRACT Marine operations traditionally rely on human intervention, a costly and disruptive method. Autonomous surface vehicles (ASVs) offer a powerful alternative, capable of operating autonomously, for extended periods, and with various sensors for various missions.
