    摘要:

    本文研究了传感器网络下网络化运动控制系统的攻击重构问题,提出了一种新颖分布式投影中间估计器去估计传感器和执行器攻击信号.引入投影算子来确定受攻击的信道集,同时设计了最小二乘算法来减轻观测器在估计过程中的计算负担.另外,引入分布式估计框架来提高算法的可伸缩性和扩展性.结果表明,该算法的估计精度和实时性分别优于现有的扩展状态观测器和梯度下降算法.最后,通过网络化运动控制系统的实验结果验证了所提方法的有效性.

    Abstract:

    This paper studies the attack reconstruction problem for networked motion control systems under sensor networks. A new distributed projected intermediate estimator (DPIE) is proposed to reconstruct the actuator and sensor attacks. A projection operator is introduced to determine the set of attacked signal channels. Meanwhile, a least square algorithm is designed to alleviate the computational burden of the observers in the process of generating new estimates. In addition, a distributed estimation framework is introduced to improve the scalability and scalability of the proposed algorithm. It is shown that both the estimation accuracy and real-time performance of the proposed algorithm are better than those of the existing extended state observer and gradient descent algorithm respectively. Finally, the experimental results of the motion control system are given to verify the effectiveness of the proposed methods.
