基于开关磁阻电机的车用ISAD系统研究

针对基于开关磁阻电机的车用ISAD系统,分析其主要工况起动助力发电,提出各工况状态下控制策略并给出仿真波形。同时采用TMS320F240型DSP和EPM7128S型CPLD构成核心控制器,最后以1kW三相6/4开关磁阻电机为样机完成起动助力发电实验,给出了实验波形和分析结论。实验结果表明,提出的控制器及其控制策略是有效的,基于开关磁阻电机的车用ISAD系统在工程实践上是可行的。

Research of Integrated Starter Alternator Damper System Used in Vehicle Based on Switched Reluctance Motor

The paper contraposes integrated starter alternator damper(ISAD) system used in vehicle based on switched reluctance motor(SRM), analyses its mostly working statuses including starter,assistor,generator, puts forward control strategies on mostly working statuses and the simulation waves are gave. The controller based on digital signal processor (DSP) TMS320F240 and complex programmable logic device (CPLD) EPM7128S is designed. The experiments on a three phases 6/4 structure SRS/G prototype are did. The waves and the analysis of results are gave. The experimental results indicate that the controller and control strategies are valid , the ISAD system used in vehicle based on SRM is feasible in project practice.
