Abstract
The purpose of this paper is to investigate high-altitude electromagnetic pulse (HEMP) insult mitigation strategies. State-of-the-art solutions currently endorse capacitor blocks on the neutral path. These devices cause system ringing which introduces unnecessary stress on the electrical grid and adjacent components. The scope of this paper is to explore and contrast five different control laws. Performance metrics for this trade study of control laws look at minimizing: i) magnetic core flux saturation, ii) voltage and control effort ringing/oscillations, iii) required energy storage, and iv) transient decay. Additionally, minimizing control effort does not necessarily imply minimized energy storage. Highlights for the results of two of the potential control designs contrast a modern linear quadratic regulator (LQR) feedback controller with a novel Hamiltonian feedback control. The novel controller produced minimal amount of energy storage required to mitigate the HEMP insult.
