The finite-time dynamic positioning controller design problem of the unmanned marine vehicle (UMV) system under switching DoS attacks is investigated. Firstly, an adaptive memory-based event-triggering communication mechanism (METCM) is designed to save networked resources in maritime environment. Second, the signals released by the communication mechanism are quantized to further reduce the bandwidth of the communication network. In addition, since adversary may have multiple attack strategies, thus a hierarchical semi-Markov process (HS-MP) is presented to capture the phenomenon of switching DoS attacks, which makes the attack model more realistic. Further, sufficient conditions are proposed for the finite-time boundedness (FTB) of the UMV system and some linear matrix inequalities are solved to determine the finite-time bounded controller gain. Finally, the effectiveness of the proposed control method is demonstrated by a simulation example.
