The paper presents the results of some theoretical and experimental studies, concerning a large class of non-linear systems (also known as systems with memory). Such systems are representing models for a few inner or outer coupling, as components of complex mechanical structures, for example gyro- stabilisators, mono-, bi- or three-axis gyroscopic guidance heads. In fact, the bi- or three-axis gyro-systems are two or three interconnected mono-axis gyro-systems. The model for a mono-axis gyro-system consists of two sub-systems: a linear one (which has good filter properties) and the non-linear one (described by a non-linear element without memory and the linear element with or without memory). The study’s objects are the non- linear systems and their issues concerning the static characteristic and couplings.
