针对集装箱龙门起重机的具体工况需求和特点,构建一种适用于集装箱龙门起重机的增程式混合动力系统,提出并分析该动力系统的能量智能控制策略,设计相应的智能控制模型.通过以动力电池组的荷电状态(State Of Charge,SOC)和集装箱龙门起重机运行能量需求为模糊输入,以动力电池组的充电功率为模糊输出,实现了对增程式混合动力系统的智能控制.仿真结果验证了该控制策略和控制模型的可行性和有效性.

Taking into account the work condition requirements and characteristics of container gantry cranes,a range-extending hybrid power system suitable for container gantry cranes is proposed. The intelligent energy control strategy of the power system is proposed and analyzed for establishing a corresponding intelligent control model,in which State Of Charge( SOC) of the power batteries and the energy demand of the container gantry crane operation are set as fuzzy inputs and the charging power of the power batteries is set as the fuzzy output to achieve the intelligent control of the range-extending hybrid power system. Simulation results verify the feasibility and effectiveness of the control strategy and the control model.
