“…During the last decade, NVEHs * Corresponding author: camille.saint-martin@univ-smb.fr have been attracting research interest because of their enhanced frequency bandwidth compared to their linear counterparts [4,5]. However, NVEHs exhibit complex dynamical behaviors making their evaluation and comparison challenging [6,7,8]. Here, we offer a new metric that assesses the performances of NVEHs while taking into account the full complexity of their nonlinear behaviors.…”

“…Referring to Figure 9a,b it is easy to find that a velocity of 54 Hz is sufficient to overcome the potential barrier and obtain a rotational solution. This solution resembles the type of vibration coherence resonance [20], where excitation frequency is less important than the amplitude important to generate a large orbit motion with a minimum of excitation energy necessary to overcome the potential barrier. For higher frequency intervals such as [9 Hz,15 Hz] and [35 Hz,45 Hz], the response angular velocity is proportional to excitation frequency.…”

“…From the application point of view, research aimed at increasing the density of recovered energy is important for systems generating small portions of energy in a fairly wide frequency band [12][13][14]. That is why energy harvesting systems with non-linear behavior are researched [15][16][17][18][19][20]. The main advantages of non-linearities introduced to the system are the possibilities to modify the resonance behavior [21,22], to obtain good off-resonance performance [23][24][25] or to attain multi-resonance [26].…”

A concept of non-linear electromagnetic system with the rotational magnetic pendulum for energy harvesting from mechanical vibrations was presented. The system was stimulated by vertical excitation coming from a shaker. The main assumption of the system was the montage of additional regulated stationary magnets inside coils creating double potential well, and the system was made with a 3D printing technique in order to avoid a magnetic coupling with the housing. In validation process of the system, modelling of electromagnetic effects in different configurations of magnets positions was performed with the application of a finite element method (FEM) obtaining the value of magnetic force acting on the pendulum. A laboratory measurement circuit was built and an experiment was carried out. The voltage and power outputs were measured for different excitations in range of system operational frequencies found experimentally. The experimental results of the physical system with electrical circuit and numerical estimations of the magnetic field of a stationary magnet’s configuration were used to derive a mathematical model. The equation of motion for the rotational pendulum was used to prove the broadband frequency effect.

A Simple Model of the Energy Harvester within a Linear and Hysteresis Approach

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.
