摘　　要：研究非线性质量切换无人艇在拒绝服务攻击下的动态记忆事件触发动力定位控制问题.首先,建立一个切换模糊模型描述非线性质量切换无人艇系统,该模型同时考虑了船舶的非线性特征及质量变化行为;然后,提出一个包含记忆项的动态记忆事件触发机制,该机制可利用动态变量的历史信息调整触发阈值,进一步节约有限的通信资源,在此基础上,构造基于该动态记忆事件触发机制的控制器以补偿海洋扰动;接着,利用多Lyapunov函数策略给出拒绝服务攻击下质量切换无人艇系统动态记忆事件触发动力定位控制问题的可解性判据,在拒绝服务攻击下,所提出控制方案能够应对网络攻击导致的通信中断问题,确保质量切换无人艇在恶劣网络条件下仍能保持动力定位性能;最后,以一艘质量切换船为例,验证了该控制方案的合理性.This paper addresses the dynamic memory event-triggered dynamic positioning control issue of a nonlinear mass-switched unmanned marine vehicle under denial-of-service attacks.Initially,a switched fuzzy model is designed to describe the nonlinear mass-switched unmanned marine vehicle.Both the nonlinear characteristics of the vessel and mass-switched behavior are considered in this model.Then,a dynamic event-triggered mechanism with a memory element is proposed.The historical information of dynamic variables is used to adjust the triggering threshold,further conserving limited communication resources.Based on this mechanism,a controller is designed to compensate for ocean disturbances.Furthermore,by employing the multiple Lyapunov function approach,a solvable criteria for the dynamic memory event-triggered dynamic positioning control issue of a mass-switched unmanned marine vehicle system under denial-of-service attacks is provided.Under denial-of-service attacks,the proposed control scheme can handle communication interruptions caused by network attacks,ensuring that the mass-switched unmanned marine vehicle maintains dynamic positioning performance under adverse network conditions.Finally,the effectiveness of this control scheme is validated by a case study involving a mass-switched vessel.
