摘要

《中国制造2025》计划要求从顾客到产品等全部环节的全面自动化。这将为生产制造系统的各个环节带来巨大挑战。在未来的加工制造领域中,全部的设备和系统应当具有对控制性和适应性的感知能力和基础智能化处理的能力。在研究中,经过关于多尺度动力学在现代加工制造系统中应用的讨论后,一个五层的功能结构被用于不确定的加工制造过程。多尺度力学包括:多时间尺度、多时空尺度以及多尺度的动力学标准。随着快速与慢速的时间尺度对设计的更多要求,不同的尺度所对应的不同控制行为也将呈现区分化。低速时间尺度下的操作需要更多的定量化手段,与此同时,高速时间尺度下的监管也需要更多高质量的手段。智能生产系统应当拥有灵活应变的能力、较好的适应能力及足够的智能化程度。这些能力需要我们通过控制性手段进行区分化处理并应用在不同方面,如智能感知、优化设计、智能学习等。最后,将一个典型的喷射点胶系统模型用于多尺度建模和控制。
