本文提出了一种创新的能量收集控制器，以增加从振动中收集的能量。能量收集是从振动结构中移除机械能的过程，这必然导致阻尼。与压电能量收集相关联的阻尼抑制机械振动的振幅并减少所收集的能量。为了解决这个关键问题，我们设计了一个能量收集控制器，保持振动振幅尽可能高，以增加收获的能量。我们提出的开关控制器的目的是故意停止开关动作间歇。我们的实验表明，所提出的控制方案成功地增加了收获的能量。该控制器的压电电压比原来的同步开关收获电感（SSHI）技术，这增加了收获的能量。与我们的控制器存储的能量是5.7倍以上，比传统的SSHI控制方案。
This paper proposes an innovative energy-harvesting controller to increase energy harvested from vibrations. Energy harvesting is a process that removes mechanical energy from a vibrating structure, which necessarily results in damping. The damping associated with piezoelectric energy harvesting suppresses the amplitude of mechanical vibration and reduces the harvested energy. To address this critical problem, we devise an energy-harvesting controller that maintains the vibration amplitude as high as possible to increase the harvested energy. Our proposed switching controller is designed to intentionally stop the switching action intermittently. We experimentally demonstrate that the proposed control scheme successfully increases the harvested energy. The piezoelectric voltage with the proposed controller is larger than that with the original synchronized switching harvesting on inductor (SSHI) technique, which increases the harvested energy. The stored energy with our controller is up to 5.7 times greater than that with the conventional SSHI control scheme.
