中文摘要： 超声波电机的优良特性使其在微型机器人的驱动控制中得到广泛的应用。由于受其摩擦驱动机理的限制，超声波电机的能量转换效率低，这严重限制了它在许多有限能量场合中的应用，如密封恶劣环境中工作的微型机器人。因此，研究振动能量采集与回馈的方法将超声波电机的振动能量回收转换成电能，并定期向密封恶劣环境中工作的微型机器人提供电能。本项目将探索研究能量回馈型超声波电机的构造理论与关键技术，并研制出至少一种能量回馈型超声波电机样机。研究内容包括：（1）能量回馈型超声波电机的工作机理与关键结构设计；（2）能量回馈型超声波电机的理论模型、设计方法；（3）超声波电机能量转换系统与储能系统耦合动力学行为；（4）能量回馈型超声波电机的驱动与控制特性；（5）能量回馈型超声波电机的制备科学与综合试验。本项目目标是研制集驱动与发电一体化的高效节能型超声波电机，为微型机器人在密封恶劣环境中的持续稳定工作

英文摘要： The excellent performances of ultrasonic motors enable their wide applications in driving and controlling micro robots in recent years. However, due to the utilization of friction driving mechanism, the energy conversion efficiency is low, which greatly limit their applications in occasions such as sealed conditions where working micro robots only have limited energy supply.In order to provide a solution for such applications, the vibration energy-recycling technology is proposed to harvest and transfer vibration energy into electrical power, and to periodically supply to the micro robots involved.In this project,we will study the basic theories and the key technologies of the energy-recycling-type ultrasonic motor, followed by the prototype development of at least one type.The research contents include: (1) The operation mechanism and the key structure design; (2) The theorerical model and the design method; (3) The coupling dynamic behaviors between the energy harvesting system and the energy storing system; (4) The driving and the controlling performances; (5) The manufacturing sciences and the comprehensive tests. The objective of the project is to develop a highly efficient and energy-saving ultrasonic motor where the driving and the energy harvesting functions are integrated.
