Deals with the theoretical observation of the dynamic behaviour of technical systems in the broadest sense.
For example, as a technical system with a certain dynamic performance, which is highly non-linear, the hydraulic system has specific behaviour. The same applies for electrical or mechanical drive systems, but also for other technical areas, such as thermodynamics, where the dynamic behaviour is illustrated through state changes.
However, cybernetics deals not only with system theory, but also the control and feedback control characteristics of these processes, i.e. with their internal transfer and processing of information, to show ways in which the respective system can be influenced in order to achieve certain objectives.
