论文摘要
储层计算是预测湍流的有力工具，其简单的架构具有处理大型系统的计算效率。然而，其实现通常需要完整的状态向量测量和系统非线性知识。我们使用非线性投影函数将系统测量扩展到高维空间，然后将其输入到储层中以获得预测。我们展示了这种储层计算网络在时空混沌系统上的应用，该系统模拟了湍流的若干特征。我们表明，使用径向基函数作为非线性投影器，即使只有部分观测并且不知道控制方程，也能稳健地捕捉复杂的系统非线性。最后，我们表明，当测量稀疏、不完整且带有噪声，甚至控制方程变得不准确时，我们的网络仍然可以产生相当准确的预测，从而为实际湍流系统的无模型预测铺平了道路。
While the ultimate goal is to produce a tensegrity more than 6 struts, e.g. a 15-bar tensegrity, past experience has demonstrated that we must first develop an innovative system that will facilitate the assembly of a general n-bar tensegrity. To be successful, we believe the development of the new assembly methodology must encompass not only the design of the clamping system but also the design of the tensegrity itself, including the struts, the springs and the spring-to-strut connectors. We therefore propose to develop the 15-bar in two phases: Phase I will be the development of an innovative assembly method, and Phase II will focus on the design and manufacture of a 15-bar tensegrity, with a new strut design probably being part of this. Longer term goals will be aimed at repackaging the wireless electronics on the new struts and adding encoders to control the phase of the motors shafts.
