Steady State for a Class of NonLinear Systems: A Bond Graph Approach

A bond graph model for a class of nonlinear system is presented. This class of nonlinear systems is characterized by states product. The steady state of this class of nonlinear systems based on bond graph models is proposed. The bond graph approach using the derivative causality assignment allows to determine the steady state of the nonlinear system in a simple and direct manner. Finally, the proposed methodology to a classical example of a DC motor is applied. However, the steady state of a more complex example represented by a manipulator with a link in a bond graph model is obtained.
