Decentralized system identification for electric power system
Electrical Engineering in Japan, 1996 AbstractResearch on decentralized control of an electric power system is important for stabilizing control problems. In particular, since an electric power system is a large‐scale nonlinear control system, decentralized (not divided) systems with cooperation should be constructed.This paper presents ways to construct decentralized systems for an ...

Advanced Engineering Materials, EarlyView.The wettability of aluminum droplets (Al) on different copper substrates (Cu), where liquid Al spreads on solid Cu surfaces to form a liquid–solid interface, is studied numerically and experimentally. The experimental and numerical results show good agreement in the fast‐spreading regime.
