An Adaptive, Multi-Rate Linear Quadratic Regulator for a Shipboard MVDC Distribution System with Constant Power Loads

Abstract

Future U.S. Navy warships will have DC electrical distribution systems. These distribution system swill include multiple layers of electronic power converters. When coupled to high-bandwidth controllers, power converters behave as constant power loads to the distribution system. Constant power loads have a negative non-linear impedance characteristic that threatens system stability. Many different single-input control schemes have been applied to DC microgrids with constant power loads. In this work we propose a centralized select-matrix, multi-rate linear quadratic regulator (LQRSM)-based control scheme to provide a flexible and adaptable controller for high-order, multi-input, and multi-rate distribution systems.
