项目摘要

The aim of this study is to investigate the mechanism of the generation of motion pattern based on the cooperation of locally controlled self-excited oscillators.First, we investigated the cooperation mechanism between self-excited oscillators from the viewpoint of frequncy entrainment. We used self-excited oscillators which is, controlled by velocity feedback with variable gain, because its mechanism to change the state of oscillation into self-excitation and vibration suppression is simple. When external force to the oscillator is small, the velocity feedback has a positive gain and self-excited vibration is generated. When external force is large and vibration amplitude reaches reference only by forced vibration, the velocity feedback actively suppresses vibration, and frequency entrainment occurs. The synchronization limit of foeced entrainment is derived from the resonance curve of forced vibration. Frequency entrainment in the plural oscillators can be treated as forced entrainment by substituting external force for the interaction of other oscillators.Then we investigated the mechanism of the generation of motion pattern. We showed any phase delay between the oscillators can be generated by apllying the control force, which can be made from properly weighted displacement and velocity of adjascent oscillators, to each oscillator. This method enables us to generate any motion pattern.Finally, we applied this method to drive vibration transportation machines, and we realized vibration transportation by cooperation of decentralized self-excited vibratory machines.

这项研究的目的是研究基于本地控制的自激发振荡器的合作的运动模式产生的机制。首先，我们从Frequncy夹带的角度研究了自激发振荡器之间的合作机制。我们使用了自振兴的振荡器，该振荡器由具有可变增益的速度反馈控制，因为它的机制将振荡状态转化为自我激发和振动抑制很简单。当振荡器的外力很小时，速度反馈会产生正增益，并产生自激发的振动。当外力大，仅通过强制振动才能达到参考，速度反馈会积极抑制振动，并且发生频率夹带。粪便夹带的同步极限来自强制振动的共振曲线。复数振荡器中的频率夹带可以通过将外力代替其他振荡器的相互作用来视为强制夹带。然后我们研究了运动模式产生的机制。我们显示振荡器之间的任何相延迟都可以通过对控制力进行放置，该控制力可以通过适当加权的位移和相邻振荡器的速度制成每个振荡器。这种方法使我们能够生成任何运动模式。在本文中，我们应用了这种方法来驱动振动运输机，我们通过合作通过分散的自我激发振动机的合作来实现振动运输。
