Abstract
With the grew of global population, the demand for electrical energy have increased exponentially in the last decades. Therefore, there is a need to search for new ways to harvest energy, even for low power consumption system. Electric energy retrieved from dynamic system have been very import due to the feedback of energy from wasted energy from the system, for example, the kinetic energy provided by vibrations, being possible to use such energy in electric components near these systems. Therefore, this work proposes to control a magnetic levitation system in order to harvest energy from a periodic motion. Depending on the magnetic force, i.e., stiffness of the system, it may become chaotic, which is a difficult way to harvest energy. Thus, the SDRE control strategy will be applied in order to control the chaotic behavior and maintain a good value of energy harvesting. Results showed the SDRE controlled the system and increased significantly the harvested power.
