论文摘要
在过去的几十年中，车辆悬架的同时振动控制和能量收集吸引了极大的研究兴趣。但是，现有的框架权衡暂停性能以进行能源回收，并且仅对窄带宽度振动有反应。在本文中，研究了一种使用球形螺钉机制的新能量再生振动吸收器（ERVA）。 ERVA系统基于具有可调节的非线性旋转惯性的旋转电磁发生器，随着振动幅度的增加，可被动地增加惯性矩。该结构可有效地收集能量和振动控制，而无需增加悬架尺寸。此外，将非线性模型预测控制器（NMPC）应用于系统，以进一步增强，我们将道路概况信息作为预览。在许多模拟中证明了基于NMPC的ERVA的性能，并证明了卓越的性能。
Simultaneous vibration control and energy harvesting of vehicle suspensions has attracted great research interests over the past decades. However, existing frameworks tradeoff suspension performance for energy recovery and are only responsive to narrow-bandwidth vibrations. In this paper, a new energy-regenerative vibration absorber (ERVA) using a ball-screw mechanism is investigated. The ERVA system is based on a rotary electromagnetic generator with adjustable nonlinear rotational inertia which passively increases the moment of inertia as the vibration amplitude increases. This structure is effective for energy harvesting and vibration control without increasing the suspension size. Furthermore, a nonlinear model predictive controller (NMPC) is applied to the system for further performance enhancement where we exploit road profile information as a preview. The performance of NMPC-based ERVA is demonstrated in a number of simulations and superior performance is demonstrated.
