为了解决日益严重的能源、污染排放问题，在航海船舶中提出混合动力船舶的动力提供方法，其本质是对船舶电机的控制，包括发电机和蓄电池之间的转换。本文将对混合动力推进系统进行分析介绍，通过滑模控制策略方法控制两者之间的转换稳定，提高蓄电池的稳定接入运行，并且通过Matlab/Simulink进行仿真分析，与PI控制进行对比。仿真分析结果表明，采用的滑模控制策略能够很好的控制混合动力推进系统的转变和控制，以及适应负荷的转变。混合动力推进系统可以较好满足船舶航行要求。
In order to solve the increasingly serious problems of energy and pollution emissions, the power supply method of hybrid ships is proposed in nautical ships. Its essence is to control the ship’s motors, including the conversion between generators and batteries. This article will analyze and introduce the hybrid power system, and control the conversion stability between the two through the sliding mode control method to improve the stable connection operation of the battery, and perform simulation analysis through Matlab / Simulink, and compared with PI control. The results show that the adopted control strategy can better control the transition and control of the hybrid power system, as well as the adaptation of the load.
