Research of a Novel Ship-loading Energy Circulatory System under Multi-process State

针对船舶航行过程中能耗大、效率低等问题,设计一种新型船载式能量自循环系统,系统以船舶航行过程中周围流场运动作为动力源将流场动能转化为电能,模型中根据航行过程状态的不断变化引入DMC-PID混合预测控制算法对系统中带传动中的传动比进行调节,最后研究在传动比控制条件下带传动船载式能量自循环系统参数特征、性能指标的变化规律。分析结果表明,通过各项性能指标分析,设计的新型船载式能量自循环系统具有一定的可行性;能量自循环系统中引入可变传动比带传动系统和DMC-PID控制以后系统性能得到了一定的提高。

For the problems of high energy consumption,low utilization in ship sailing process,a new type of ship-loading energy circulatory system is presented,the system with the process of the flow field around the sports field of the ships as a power source kinetic energy is transformed into electrical energy.In the model,according to the changing of the sailing process state,the DMC-PID mixed prediction control algorithm is introduced to adjust the transmission ratio of belt drive in the system.Finally,the variable law of the belt drive parameters characteristic and performance indicators of the ship-loading energy circulatory system under the condition of transmission ratio under control are studied.The results show that the designed novel ship-loading energy circulatory system is feasible through analysis of performance indicators,since the introduction of variable transmission ratio belt drive system and DMC-PID control system in the energy circulatory system,the performance of the system is improved.
