摘　　要：研究了具有参数摄动、互联影响等不确定因素的组合系统的分散控制问题·在假设系统的不确定性有界且关联项不匹配的前提下,给出了系统的一种分散变结构控制算法,实现了组合系统的全局渐近稳定·该算法克服了以往由于关联项匹配而带来的局限性·该控制器设计简单,计算量小,易于工程实现·仿真结果表明控制器的设计是有效的·The design of a decentralized variable structure controller for interconnected systems was investigated. Based on variable structurecontrol (VSC) theory and by exploiting the structure of interconnected systems, a concise approach of decentralized VSC was presented. The design of decentralized variable structure controller required the uncertainties of the systems were bounded, but the interconnected item and the uncertain interconnected item were not required to be matched. The designed controllers guaranteeing the closedloop systems are global asymptotically stable. The design approach is simple.
