制造系统的控制结构及其发展趋势

为了探讨制造系统中控制结构的研究现状及发展趋势，以制造系统的发展历程为背景，介绍了制造系统及其控制结构的基本概念．根据制造系统对控制结构的要求，对制造系统的集中控制、递阶控制和非等级控制等三种基本控制结构的特征及优缺点进行了综述，对非等级控制结构的设计原则和控制单元之间控制职责的分配、协调方法等最新研究动态进行了跟踪整理，对混杂控制的几种常见形式进行了归纳，最后指出了控制结构在应用中存在的主要问题及控制结构研究的热点和发展趋势．

Control Architectures for Manufacturing Systems and Their Evolution

The general concept on manufacturing systems and their control architectures are introduced in order to inquire into the evolution of control architectures. According to the demands of ma nufacutring systems upon a control architecture, the characteristics and merits of the three kinds of fundamental control architectures, including centralized control, hierarchical control and heterarchical control, are reviewed. Based on the summarization of recent evolution of control architectures for manufacturing systems, some major problems in application, some hot spots of research and possible future directions of control architectures are projected.
