Taking the permanent magnet synchronous motor (PMSM) of the unmanned surface vehicle (USV) and its characteristics of the propeller load as study object, the sliding mode variable structure control was introduced in PMSM propulsion system to improve the dynamic performance of USV propulsion system. The correctness and effectiveness of the design of sliding mode variable structure control USV propulsion system was verified by MATLAB/Simulink simulation analysis. Simulation results show that in the shippropeller composite load of PMSM propulsion system, the sliding mode variable structure controller can not only overcome the shortcomings of setting PI parameters difficultly, large speed and torque overshoots in the dynamic process, but also enhance antiinterference ability of the USV propulsion system under complex sea conditions and raises the dynamic and static performance of the system.
