摘要:
 研究提高无刷直流电机( BLDCM) 通用性的方法,基于电机和逆变器 HIL 建模的原理,设计硬件在环 ( HIL) 实时仿真实验。采用标幺化建模方法,避免由于仿真电机的更换所造成的数据溢出; 建立电机 HIL 模型,使用实物电机中的非理想反电势波形,模拟实物电机的输出; 建立逆变器HIL 模型,增加续流和关断过程,适用于多种运行状态; 最后,搭建了电机参数实时发送上位机平台,方便电机参数的修改和实时加载,防止定点数重复计算,提高建模效率。将 HIL 平台与全实物实验平台进行了实验对比,结果表明,HIL 实时平台能准确仿真出不同反电势波形的 BLDCM 在不同控制方式下的运行过程,在实时性、通用性和精度方面符合需求。
Abstract:
 Based on the principle of motor and inverter HIL modeling,the simulation of a brushless DCmotor ( BLDCM) with a hardware in the loop ( HIL) is studied to improve the versatility. Firstly,themethodology of per-unit modeling that avoids data overflow caused by the change of motors enhanced theuniversality of the model. Secondly,non-ideal back electromotive force ( EMF) shapes of physical motorwas employed in the real-time BLDCM model to simulate the output of the physical motor. Next,the in-verter HIL model,considering the freewheeling and shutting down process,was suitable for all types of op-eration conditions. Finally,
a platform for delivering parameters was created to modify the motor parametersand change real-time load online conveniently,which avoid the repeated fixed point computation of param-eters and improves modeling efficiency. Comparing the HIL platform and full physical experiment platformunder same conditions,
the results show that the HIL platform can simulate different types of operations ofBLDCM with different kinds of back EMF waveforms and thus meet the requirements in terms of real-time,versatility and accuracy.
