“…This approach made it possible to create almost identical models for different physical entities and apply similar research methods to them, in particular, mechanical [12,6] or mechatronic systems [11]. For example, the system of two differential equations of the first order with defining and constant parameters , , , , , , a A b B R c D is a basic mathematical model of many multi-parameter systems of diverse purposes, which, using a finite number of assumptions, are reduced to two-parameter systems.…”
