“…As seen in this figure, the proposed module is made up of resources and experimental setups tailored to provide support for communication network evaluations of control systems. In the following subsections, the CEF communication network module will be used to replicate the behavior of an 'ideal' hardware-based communication network deployed to test the performance of a distributed power and energy management system for MVDC ship power systems [7].

Interest by the U.S. Navy in the development and deployment of advanced controls in future shipboard platforms has motivated the development of the Controls Evaluation Framework (CEF) for use in investigating dynamics present in complex automated systems. This paper reports on the implementation and investigation of a communication network component within the CEF. This implementation is designed to augment the CEF's available feature set, permitting the exploration of various communication conditions on advanced control performance. Results obtained from controller hardware-in-the-loop testing are presented and analyzed to demonstrate performance characteristics pertaining to the implemented module.

“…P OWER converters are an essential component of microgrids such as Plug-in Hybrid Electric Vehicles (PHEVs) [1], [2], More Electric Aircrafts (MEAs) [3]- [8], electric ships [9]- [14], distribution grids [15]- [18], etc. Cascaded control is a very popular control strategy for power converters, which consists of PI/PID controllers operating at two different timescales (inner and outer) [19]- [21].…”

A feed-forward sensitivity conditioning control strategy is analyzed in this paper and it is applied to power electronic converters. The feed-forward term is used to improve closed loop systems, such as power converters with cascaded inner and outer loop controllers. The impact of the feed-forward sensitivity term is analyzed using singular perturbation theory. In addition, the implementation of the feed-forward control term is addressed for practical systems, where the number of inputs is generally not sufficient for exact sensitivity conditioning. Simulation results are presented for a buck converter with output capacitor voltage regulation and a Permanent Magnet Synchronous Machine (PMSM), used as a generator with an active rectifier. Finally, experimental results are presented for the buck converter, demonstrating the advantages and feasibility in implementing the approximate sensitivity conditioning term for closed loop power converters.

“…DC distribution allows contribution from a number of on-board power sources to supply the PFN of the EMRG as opposed to a single dedicated source and is therefore beneficial for the ATK-R. The challenge of DC is the potential of power system instability when high ramp loads induce voltage drop caused by unbalanced power flow, advanced energy management being a possible solution (Vu, Gonsoulin, Perkins, et al 2017).…”

SynopsisHigh-power electric weapons, such as the ElectroMagnetic RailGun (EMRG), laser and High Power Microwave devices are moving closer to practical utilisation by navies, and prototype EMRG systems are being tested at militarily useful energy levels. Previous work in the UCL Department of Mechanical Engineering includes; preliminary design studies for surface combatants with an all-electric weapons outfit; and detailed marine engineering analysis, to PhD level, of the implications for future power and propulsion systems of these weapons. Design studies for electrically armed ships have generally examined large destroyer-sized surface combatants, with significant installed electrical power. This paper describes a concept design study for a small corvette-sized combatant, ATK-R, developed as the "minimum sized ship" capable of supporting an EMRG as its primary armament This paper describes the UCL ZEOLIT design tool, the ship design impacts and marine engineering integration of this future concept including the use of Energy Storage Systems (ESS) and the choice between power limited (Patrol vessel -like) and power dense (Fast attack craft -like) power and propulsion systems.
