Abstract
基于独特漏磁设计的漏磁可控永磁(Flux Leakage Controllable Permanent Magnet, FLC-PM)电机, 具有宽调速和高输出转矩特性, 能够满足电动汽车多变工况下广域高效的运行需求. 然而, 由于FLC-PM电机特殊的漏磁磁路设计, 使其无位置传感器控制驱动系统存在周期性谐波干扰、非周期性谐波干扰和环路延迟问题, 从而严重影响转子位置估算性能. 针对上述问题, 本文提出一种基于自适应扰动补偿观测器的无位置传感器控制方法. 首先, 提出自适应扰动迭代学习控制方法, 通过迭代学习增益自适应扰动变化, 以抑制周期性干扰和非周期性干扰的谐波, 降低电流的谐波含量. 此外, 设计自适应补偿位置观测器, 对估计位置误差进行实时在线观测和补偿, 在提高FLC-PM电机转子位置估计精度的同时, 改善驱动系统的动态性能. 最后, 通过实验验证所提控制方法的有效性和可行性.
