摘要
分散控制方法和变结构控制方法两者优点的结合使得分散变结构控制在大系统研究中得到了广泛的重视．针对各个子系统均为多输入情况，研究了不确定性关联大系统的分散变结构控制方法．基于开关平面的等价性，提出了关联大系统的分散滑动模态全局可达条件．并针对子系统不确定性的界已知及未知两种情况，提出了分散变结构控制算法．该方法克服了以往控制方法中需已知线性关联函数或不确定性关联的界的缺陷．
The advantages of both variable structure control and decentralized control have motivated us to investigate decentralized variable structure control methods for uncertain interconnected systems. A set of global reaching conditions based on the linear transformation of sliding surface for multi input subsystems are presented in this paper. The proposed decentralized variable structure control laws can be used to deal with the problems of large scale systems with unknown interconnections.
