摘要
针对一类耦合时滞复杂网络,基于变结构控制研究其同步问题.首先,利用系统的左特征向量函数设计切换面,使网络的运动轨线在期望的同步轨道保持稳定;然后,针对网络中的非线性项已知和未知时,分别设计相应的滑模控制器,使从任意时刻出发的动态网络轨线都能在有限时间内同步到达期望的轨道;最后,利用所设计的控制器对两个算例进行仿真,仿真结果说明了所设计控制器的有效性.
According to a class of coupling delays complex networks, the synchronization problems are studied based on variable structure control. The switching surface is designed by using the left eigenvector function of the system, which can assure the state of the network keep stable at the desired synchronization orbit. The sliding mode controllers are designed for the network with known and unknown nonlinear term, which can assure the network state from arbitrary time hitting the desired switching manifold in finite time. Finally, two examples are simulated by using the designed variable structure controller, the results demonstrate the effectiveness of the proposed controllers.
