摘要
分析了对转永磁无刷直流电动机和对转螺旋桨的数学模型,在Matlab/Simulink平台上,建立了对转电机和对转螺旋桨仿真模型,并对转速电流双闭环调速系统带螺旋桨负载进行仿真分析,仿真结果表明:内外轴系统的转动惯量应尽量相同,可提高推进系统的响应速度;合理地设计推进系统,可使内外转轴转速相等,提高推进效率。
Based on the analysis of the mathematical model of the contra-rotating BLCDM,the BLDCM model was established by the modular design in Matlab/Simulink,and the simulation experiment was accomplished with contra rotating propeller（CRP） loads.The results show that it can increase the response speed of the propulsion system if the internal and external shaft systems are of the same moment of inertia and that the rational design of propulsion systems can make the inside and outside rotor speeds equal,thus improving the propulsive efficiency.
