摘　　要：针对一类具有未知参数和外界干扰的时滞耦合复杂网络,通过设计具有积分环节的滑模面和自适应控制器,实现了该时滞耦合复杂网络对外部参考信号的追踪控制.所设计的控制器能够保证动态复杂网络从任意初始状态出发都能达到滑模面上且趋于稳定.控制器的设计能有效克服系统模型不确定和外部干扰的影响,具有一定的鲁棒性.数值仿真结果得出各个节点都能追踪参考信号,追踪误差随时间衰减为零,验证了该控制方法的有效性.The tracking control of a delay coupling complex network with unknown parameters and external disturbances was researched in this paper.By the designed appropriate sliding mode surface and adaptive controller,the delay coupling complex network could track the external reference signal exactly.The dynamic complex network could reach the sliding surface from any initial state and tended to be stable by the designed controller.The proposed controller had strong robust property since it was beyond the impact of model uncertainty and external perturbation.The numerical simulation results showed that each node could track the reference signal,and the tracking error decayed to zero with time,which verified the effectiveness of the control method.
