摘要
针对复杂大系统控制中,现有牵制控制策略仅依据拓扑结构而存在的不足和控制器设计中控制参数选择简单(视为常数)的问题,引入了能量指数的概念,提出一种新的牵制控制策略—–能量指数法.该方法同时考虑节点对于网络的贡献力和节点的网络特性,给出了引入能量指数后的网络动态模型描述,并将节点能量指数用于自适应控制器设计,得到了控制律设计新方法.与现有方法比较,所提方法可使系统收敛更快,更容易实现同步,从而表明基于能量指数的牵制策略和自适应控制器设计方法均是有效的,在电力、交通以及传染病防治等各种复杂网络中都具有实际应用价值.
In complex network systems, two problems in previous studies exist, one is the shortage of pinning control, the other is simply set controller's parameters as constants. Therefore, a new method, energy index pinning scheme is proposed, which both considers network's degree and single node energy. A complex system dynamic model considering energy index is obtained. Furthermore, a new method of the law of controller in designing controller is given. By the comparison with the pervious methods, better performance is obtained. Theory analysis and numerical experiment show that the proposed method is more efficient and practical.
