摘要：The basic concepts and advantages of more/all electric aircraft （M/AEA） are briefly addressed. The combined starter/generator （CS/G） system is introduced as a key technology to enable M/AEA. Some important performance requirements for CS/G system are obtained. Based on these requirements, a high speed switched reluctance machine （SRM） is designed to operate as a starter/generator. The entire design process is mainly divided into two stages： electromagnetic design and thermal design. In electromagnetic design stage, the electromagnetic structure and dimensions of the machine and the number of phase winding turns per pole are obtained; the topology and main technical details of the converter are briefly introduced as well. In thermal design stage, a liquid-cooling system is designed based on the thermal analysis of the machine. In the end, the performances of the designed SRM are basically verified by simulation. To get high performances, the exciting angles are optimized in two different operating modes respectively, and the optimized performances in the motoring mode are given as well.

摘要：为提高电动车(EV)传动系统的整体性能,设计了用于内埋式永磁同步电机(IPMSM)的自适应控制器。根据IPMSM的交、直轴电感随着定子电流的变化而变化的特点,为实现最小损耗的电流控制,进行了电机参数的有限元(FEM)计算。控制器参数被保存在一个二维表中,根据定子电流自行校正电机的交、直轴电感值,并以查表法获得相应的控制器参数。部分控制系统组件实现在现场可编程门阵列(FPGA)中。结果表明:自适应控制器可以很好地抑制电流的超调,同时由于FPGA也部分地取代了微控制器的功能,使得该系统具有更快的响应速度。
