Derivation of signals is often required to control various dynamic objects [1–8]. Derivation allows increasing the stability of the system, since it allows to react not only to the actual increase in the control error, but also to take into account the tendency of growth or reduction of this error. Derivation increases the margin of stability in phase. There are methods of designing regulators based on multiple derivations. Some researchers categorically protest against this, pointing out that multiple derivations raises noise levels, other researchers argue that derivatives of arbitrarily high order are useful. Due to the development of digital technology, a general transition to digital control systems is inevitable, with total abandonment of analogue technology (except for ADC and DAC) for these purposes. In connection with this, it is important to study the causes of the generation of noise during multiple derivations and to estimate the level of these noises. This paper carries out these studies by modeling in the VisSim program, which, by its action algorithms, is identical to that of the digital controller.
