This paper deals with the synchronization control of power complex networks with switching parameters. In the meantime, the node state constraints are considered during the synchronization process. Admittedly, synchronization problem encountered in power complex networks is becoming progressively important due to the increasing connection and disconnection operations resulting from sustainable energy and controllable load. Hereon, the network model considering switching parameters of each node is established to describe the topology variation of power systems that may be confronted in practical terms. Then, by utilizing the adaptive backstepping technique with a barrier Lyapunov function (BLF), a novel synchronization controller is constructed recursively which accomplishes the nodes full states tracking within the predefined transient behavior. Owing to the characteristic of BLF, the designed controller as well as its adaptive law could guarantee both the constrained state of each node restricted by a prescribed range and the synchronization performance. Meanwhile, the bounded output of the system could track the desired trajectory. Finally, scenario simulations are performed to demonstrate the effectiveness and superiority of the proposed method.

本文研究了具有切换参数的电力复杂网络的同步控制。同时，在同步过程中考虑了节点状态约束。诚然，由于可持续能源和可控负载导致连接和断开操作的增加，电力复杂网络中遇到的同步问题变得越来越重要。在此基础上，建立考虑各节点切换参数的网络模型来描述电力系统在实际中可能面临的拓扑变化。然后，通过利用具有障碍李雅普诺夫函数 (BLF) 的自适应反推技术，递归地构建了一种新颖的同步控制器，该控制器在预定义的瞬态行为内完成节点的全状态跟踪。由于BLF的特性，设计的控制器及其自适应律可以保证每个节点在规定范围内的约束状态和同步性能。同时，系统的有界输出可以跟踪所需的轨迹。最后，进行场景模拟以证明所提出方法的有效性和优越性。
