Control Strategy of Three-Phase AC/DC Voltage-Source Converters Based on Storage function

In order to improve the properties of AC/DC converters, scholars in deferent countries have began to apply nonlinear control theory based on storage. function to AC/DC converters. For this purpose, this paper introduces the study status of three phase AC/DC Voltage-Source Converters based on storage function, which includes Lyapunov control theory, passivity control theory using Euler-Lagrange(EL) model and port controlled Hamiltonian with dissipation (PCHD)model, And proposes a new design method of passivity controller based on EL model of AC/DC converter. Meanwhile this paper analyzes nonlinear control strategies above.
