In the design of hybrid vehicles, it is important to identify proper component sizes along with the optimal control. When the design search space is large, exhaustive optimal control strategies, such as dynamic programming (DP) is too time consuming to be used. Instead, a near-optimal method that is orders of magnitude faster than DP is needed. One such near-optimal method is developed and presented...
Shipboard electric propulsion systems experience large power and torque fluctuations on their drive shaft due to propeller rotational motions and waves. This paper explores new solutions to address the fluctuations by integrating a hybrid energy storage system (HESS) and exploring coordinated power management. A propeller and ship dynamic model, which captures the underlying physical behavior, is...
