摘要
在分析发动机起动动力学模型及开关磁阻电机(SRM)模型的基础上,通过Matlab/Simulink分别建立了发动机与开关磁阻电机的仿真模型。为了得到外界温度不同时发动机的起动阻力矩变化趋势,改变了发动机的起动外部温度。发动机-开关磁阻电机综合建模分析结果表明:发动机-开关磁阻电机集成系统能够满足发动机起动动力需求,实现发动机冷机状态下的快速起动。
Based on the analysis of the engine starting dynamics models and the switched reluctance motor(SRM) models, this thesis built the engine-SRM simulation model via Matlab/simulink. By changing environment temperature during the engine starting process, it obtains the engine' s starting moment of resistance in different temperatures. The analysis of Engine -SRM model indicates the En- gine-SRM integrated system is able to meet the id start under cold start. power demand of engine starting and can realize a rap-id start under cold start.
