无轴承异步电机转子电阻自适应在线辨识
|
摘要
针对无轴承异步电机悬浮性能受转子电阻变化影响的问题,提出了一种基于悬浮力指令观测的无轴承异步电机转子电阻自适应在线辨识方法。分析了转子电阻变化对转矩绕组气隙磁链辨识影响的机理,并利用悬浮控制系统中悬浮力指令对转矩绕组气隙磁链敏感的特性,通过对悬浮力指令的实时观测实现转子电阻自适应在线辨识。搭建了无轴承异步电机实验平台。实验结果表明:采用转子电阻自适应在线辨识方法后,无轴承异步电机转子径向位移峰峰值降低了60%。
Bearingless induction motors always suffer from the influence of rotor resistance variations.An adaptive online rotor resistance identification method is developed here based on an observer of the suspension force commands.This study analyzes the influence of the rotor resistance variation on the air-gap flux identification.Real-time online identification of the rotor resistance is based on observations of the suspension force commands,which utilizes the principle that the suspension force commands are sensitive to the air-gap flux in the torque windings.Tests of a bearingless induction motor show that the peak-peak displacements of the rotor are reduced by 60% by this adaptive online rotor resistance identification method.
