Electrical model is solved by this approach at the level of its physical behavior. In this paper the method of generation of state equations system is discussed. Model of a simple electrical RLC circuit consisting of a resistor, an inductor, and a capacitor is taken. The differential equations describing the dynamics of the system are obtained in terms of the states of the system. http://pubs.sciepub.com/automation/3/3/4/automation-3-3-4.pdf Modeling of dynamic systems Bond Graphs energy modeling state equation
