In this article, a model of an energy harvester, the mechanical part of which is an inverted pendulum, is proposed. We investigated the stability of a linearized system. It was proven that the stabilizing control of the pendulum, based on the feedback principle, enables the stabilization of the system. We have identified the zones of stability and the amplitude–frequency characteristics. In the second part of this article, a generalization of the dynamic system for the case of the hysteresis friction in the mechanical joint is considered. The role of nonlinear effects within the design Preisach model and the phenomenological Bouc–Wen model is shown.

In this work, a simple model of energy harvester transforming the energy of unstable mechanical vibrations into useful electric energy is proposed. The mechanical part of the system is presented in the form of an inverted pendulum. The electric part consists of a converter of mechanical energy based on a direct piezoelectric effect, and a payload. The dynamics of the system is considered in the linearized production, the areas of stability are determined, various dynamics modes in the parameter space are identified. It was established that the stabilizing pendulum of management based on the principles of feedback allows you to transfer the system into a stable mode of functioning. The optimal characteristics of the system that meets maximum power were found.
