基于PMSM的双螺旋桨USV推进系统建模与仿真

Modeling and simulation of twin-propeller unmanned surface vehicle propulsion system based on PMSM

以固定双螺旋桨无人水面艇(USV)的推进系统为研究对象,以永磁同步电机为推进电机,结合双螺旋桨USV的运动特点与操纵控制原理,设计一种以控制推进电机转速为核心的双螺旋桨推进系统控制方案,通过协调控制左右推进电机的转速实现对USV航速与航向的控制.仿真结果验证了所设计的双螺旋桨USV推进系统控制方案的正确性和有效性.

Taking the propulsion system of the fixed twin-propeller unmanned surface vehicle（USV） as the study object,the permanent magnet synchronous motor as the propulsion motor,and combining the characteristics of the twin-propeller propels USV and the control principle of the maneuvering,a control scheme of twin-propeller propulsion system was designed,which took the control of motor speed as the core.The speed and heading control of USV can be realized by coordinated control of the speed of the motor. Simulation results verify the correctness and effectiveness of the proposed control scheme of the twin-propeller USV propulsion system.
