What is a modulated energy storage element?

The reason for this restriction is that a modulated energy-storage element would mean that the total energy in a system would be a function of the modulating input or set of inputs. Consequently, the total energy in the system would not be equal to the net power flow in across the system boundaries..

Generalized Energy Variables

Modulated Energy Storage is Prohibited Previously we encountered the use of modulated power sources to describe how a control system might influence the energy supplied to or removed from a system. When we consider energy-storage elements, an important restriction must be emphasized: modulation of energy storage elements is prohibited.

Which energy storage element does not give rise to a state variable?

Conversely, any energy storage element which must be described using a derivative operation will not require an independent initial condition and therefore will not give rise to a state variable; energy storage elements which have derivative causality are dependent.

Chapter 7: Energy Storage Elements

OVERVIEW. The circuits examined so far are referred to as resistive circuits because the only elements used, besides sources, are resistances. The equations governing these circuits are algebraic equations because so are Kirchhoff''s laws and Ohm''s Law. Moreover, since resistances can only dissipate energy, we need at least one independent source to initiate any voltage or

For an energetic system the state variables must at least uniquely define the energy stored in the system. The minimum number of state variables required is determined by the number of independent energy storage elements in the system model.
