Abstract

A method for adjusting frequency-regulated drives with the synchronous reluctance machine with independent excitation is proposed using the KhPT-250 cold tube reducing mill and traction drive of a Gazelle-Next electric vehicle as example; the method consists in independent adjustment of the phase currents with the subsequent identification of parameters of the control object by methods of frequency identification. It has been shown that, with independent control of the excitation currents and the anchor reaction, the cross links between phase current control loops can be neglected, which can be accounted for by the large bandwidth of the uniform pass-through frequency of the phase current control loops and the weak influence of phase windings located in the interpolar gap on the operation of the phase windings that currently located above the pole. It has been shown that when the drive operates at high speeds, a significant decrease in the proportionality coefficient between the magnitude of the electromagnetic moment and current is observed, which is explained by the finite speed of the phase current control loop. When adjusting the electric drive control system with dual-zone speed control, it has been suggested to introduce a correction for the anticipatory effect of the phase current in order to provide a constant relationship between the anchor component of phase current and the magnitude of electromagnetic moment.

具有独立励磁的同步磁阻电机的电驱动控制系统

摘要

以KhPT-250冷轧管减速机和瞪羚Next电动汽车的牵引驱动为例，提出了一种具有独立励磁的同步磁阻电机调频驱动的方法。该方法包括独立地调节相电流，随后通过频率识别的方法识别控制对象的参数。已经表明，通过独立控制励磁电流和锚定反应，可以忽略相电流控制回路之间的交联，这可以通过相电流的均匀通过频率的大带宽来解决。控制回路以及位于极间间隙中的相绕组对当前位于极点上方的相绕组的运行的影响较弱。已经表明，当驱动器高速运行时，观察到电磁力矩和电流之间的比例系数显着降低，这可以通过相电流控制环的有限速度来解释。当调整具有双区域速度控制的电驱动控制系统时，建议对相电流的预期效果进行校正，以在相电流的锚定分量和电磁矩的大小之间提供恒定的关系。 。
