Abstract In this paper, an electronic circuit based on Macek equations was developed in which the phenomenon of hyperchaos was observed. Synchronization of signals was applied using the technique optimal linear feedback control (OLFC) and embedded in digital signal processor (DSP), with the circuit with hyperchaotic behavior as a master system and a periodic slave…
Part of introduction With the increasing demand for energy consumption in recent years, several areas of science have been looking for the production of clean and renewable energy. In this context, several devices are used, such as converting mechanical movement of sea waves [1–3] and portal frame systems [4–7].However, many of these devices contain piezoceramic…

Abstract: Due to the broadband response characteristics at low levels of excitations, nonlinear multistable systems have garnered a great deal of attention in the area of energy harvesting. Moreover, various performance enhancement strategies of multistable harvesters have been proposed and discussed extensively for systems with perfectly symmetric potentials. However, it is very difficult or even…

Lectures: Prof. Damian Gaska (Silesian University of Technology) “Nonlinear effects in vibration energy harvesting” Abstract: Prof. Damian Gaska (Silesian University of Technology) “Nonlinear effects…
Abstract: The special issue entitled “Mathematical modelling, nonlinear dynamics, bifurcation, synchronization and control of mechanisms driven by power supply,” published by The European Physical Journal: Special Topics (EPJST), aims to bring into discussion works involving nonlinear and dynamic and chaotic behaviors, which are frequently found in mechanical and electromechanical systems, nonlinear circuits, and biologically inspired…
10-13 April 2022 four scientists of Lublin University of Technology will visit Dublin to talk about European scientific projects, prepare research results for a new, joint journal article and have workshop on Energy Harvesting which will take place on 12 April with the following presentations: Grzegorz Litak – Energy Harvesting with multiple resonators Andrzej Koszewnik…
Abstract: In the paper, a new 3D energy harvesting system is provided. This work discussed the Lagrange approach to derive the differential equations of motion in the case of energy harvesting systems. An electromechanical system consists of a mechanical resonator, a piezoelectric transducer and electrical circuit with the load resistor. A flexible slender rod clamped…
