In this first part, this article defines the concept of energy as a
fundamental measure of the existence of matter and on that basis defines
the concept of a system solely as a pair consisting of an energy source
and an energy consumer. The notion of an invariant controlled system is
introduced and its modeling by means of an RLC system determines the
energy equations in a stable and transitive state of this invariant
system. In the second part of the article with subtitle
Electromechanical Dualism. The Universality of Energetic Equations, with
the help of modern altebra, is proved the versatility of the electrical
model of the system. The article offers a new philosophy of the concept
of control in the general dialectical sense of the word.
