High-energy orbit sliding mode control for nonlinear energy harvesting

Vibration energy harvesting has extensive application prospects in many significant occasions, such as mechanical structure health monitoring, vehicle tire pressure IoT devices and human monitoring. The nonlinearity is an effective method to improve the efficiency where there are low- high-energy orbits multi-solution region of system. harvested power will be increased significantly when system guided from low-energy orbit orbit. sliding mode control regarded easy, robust adaptive for jump, but implementation this nonlinear not been discussed. This paper proposes a through rotatable magnets actuated by micro-motor. electromechanical model mono-stable bi-stable systems with identified restoring force established design algorithm enhancing performance. Simulation experiment results demonstrate that have positive influence on reaching both within region. Moreover, actuates small short time little theoretical consumption energy. research provided potential practical jump harvesting.
