The invention provides an inertia adaptive optimization control method for electric propulsion of a hydrogen fuel cell ship, and the method comprises the steps: building an equivalent output model of each power source during the steady-state operation of the hydrogen fuel cell ship, taking the equivalent model as a mixed potential function, and analyzing a system signal stability criterion; inertial parameters and damping parameters required by the system based on the mixed potential function are obtained by inputting ship working conditions and hydrogen fuel cell working conditions; power output is realized by performing frequency division control on demanded power in the system; and an energy storage unit in the system is controlled by a virtual direct current machine, so that the inertia requirement of the system is realized, and the dynamic characteristic of the system is improved.
本发明提供一种氢燃料电池船舶电力推进船舶惯性自适应优化控制方法,通过建立氢燃料电池船舶稳态运行时各个功率源等效输出模型,将等效后的模型作为混合势函数对系统信号稳定判据进行分析,通过输入船舶工况和氢燃料电池工况得到基于混合势函数的系统所需惯性参数和阻尼参数;通过对系统中需求功率进行分频控制,实现功率输出;再通过对系统中储能单元采用虚拟直流机控制,实现系统的惯性需求,以提高系统动态特性。
