中文摘要：

研究集群攻击下的控制传感网络稳定控制算法，可以提高控制系统的稳定性。外部集群攻击下的控制传感网络失稳PID控制难以满足高精度控制要求，无法达到理想的控制效果。提出一种更为精准的适用于集群攻击的传感网络稳定控制算法。依据大规模集群攻击伪装行为的特性，构建传感网络稳定控制模型，引入遗传算法与PID控制理论相结合，搜索模型最优解，实现对集群攻击下的控制传感网络稳定的有效控制。实验结果表明，改进的控制方法可以减小控制过程的信号扰动，提高传感网络稳定性与控制精度，具有较强的鲁棒性。

英文摘要：

The stability control algorithm of sensor network under the group attack is research,which can improve the stability of the control system. It′s difficult for PID control to control the sensor network stability for sensor network under the group attack to meet the requirement of high precision control,which can't achieve ideal control effect. Therefore,a more accurate sta?bility control algorithm against cluster attack to sensor network is proposed. According to the disguised behaviour features of large?scale group aggression,the sensor network stability control model was constructed,in which the genetic algorithm was intro?duced to combine with PID control theory and search the optimal solution of the model,so as to realize the effective control of the sensor network stability under the group attack. The experimental results show that the improved control method can reduce the signal disturbance in control process,improve the sensing network stability and control accuracy,and has strong robustness.
