FOC SDK 4.1上的ICS和霍尔传感器有什么限制吗？

嗨，


我们正在使用带有ICS电流检测和状态观察器+ PLL的FOC SDK 4.1。具有21极对和11mOhms和Ls0,017mH的电动机可以很好地运行到6000rpm。
现在使用霍尔传感器改变速度/反馈以改善启动会给电流调节带来一些问题。启动工作完美，电流接近正弦波达1800 rpm（观察者+ pll更完美）。在较高的RPM下，相电流看起来像正确的位置是不正确的。
电流的幅度非常不同，并且在短时间内与速度不同步，然后与高电流幅度同步
。
ICS和霍尔传感器有任何已知的限制吗？当前/霍尔过滤或引擎设置的变化没有带来任何改进
。

任何帮助都会很棒。

Hi,


we are using FOC SDK 4.1 with ICS current sensing and State Observer + PLL. A Motor with 21 pole pairs and Rs 11mOhms and Ls 0,017mH runs up to 6000 rpm very well.
  Now changing to Speed / Feedback with Hall Sensor for improved startup give some problems in current regulation. Startup works perfect, currents are near sinusoidal up to 1800 rpm (more perfect on observer + pll). On higher RPM the phase currents look like positon is not right calculated.  
The amplitudes of the currents are very different and are not synchronous with the speed for a short time, then be synchronized hard with high current amplitude
.
Are there any known limitations with ICS and Hall sensors? Change in the current/hall filtering or engine setups brought no improvement
.

Any help will be great.
