Brayton-Moser Equations and New Passivity Properties for Nonlinear Electro-Mechanical Systems

Abstract

This paper presents an alternative framework for a practically relevant class of nonlinear electro-mechanical systems. The formalism is based on a generalization of Brayton and Moser’s mixed-potential function. Instead of focusing on the usual energy-balance, the models are constructed using the power flowing through the system. The main objective is to put forth the mixed-potential function as a new building block for modeling, analysis and controller design purposes for electro-mechanical systems
