水下无人航行器电动力推进系统启动暂态过程建模与仿真

在水下无人航行器电动力推进系统研发过程中,推进电机的启动性能需要进行反复测试与验证,造成了研制周期长、成本高。针对这个问题,提出了一种利用计算机仿真技术对电动力推进系统启动性能进行测试与验证的方法,建立了电动力推进系统的数学模型并利用SIMULINK对电动力推进系统的启动暂态过程进行了仿真计算。仿真与实验结果证明：该模型可以替代电动力推进系统启动性能测试实验,达到缩短研制周期与降低成本的目的。

Modeling and Starting Transient Process Simulation of Electric Propulsion System of UUV

At present,there are some problems such as long period and high cost in the design and design-making electric propulsion system of UUV,because the developments of electric propulsion system need the shipping experiment,in which starting transient process is an important part.In this paper,a method is provided to test the character of the propulsive motor by computer simulation,and the mathematic models of the electric propulsion system was established,and the starting transient process of electric propulsion system of UUV was simulated by SIMULINK.The research shows that the model could replace the shipping experiment to shorten the design-making cycle and depress the cost.
