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...
