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 combination of the decentralized control method and the variable structure control method makes the decentralized variable structure control widely valued in large-scale system research. Aiming at the multi-input conditions of all subsystems, the decentralized variable structure control method for uncertain large-scale interconnected systems is studied. Based on the equivalence of switch planes, a globally distributed decentralized sliding mode (GSM) global availability condition is proposed. Aiming at the known and unknown circumstance of subsystem uncertainties, a distributed variable structure control algorithm is proposed. The method overcomes the defects in the past in the control method that the known linear correlation function or the uncertainty relation needs to be known.
