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 ...

Closed-loop correction strategy for commutation deviation of BLDC motor based on internal power factor angle detection

Energy Reports, 2023
The first-order inertia of the armature winding of the brushless DC motor will cause current offset, which will reduce the electromagnetic torque. In the sensorless drive of brushless DC motors, correction of commutation point is an effective solution to
