[Feature] 支持 无感 吗? #10
Comments
目前还不支持无感,后续可以考虑增加这个feature。原因是无感并不适合低速场景,而本miniFOC项目主要是为低速如关节电机场景设计的。 |
miniFOC v2.0.2版本即将支持无感,请关注dev分支。 |
在这种低速的场合,无感的成本反而会更高。虽然违反直觉,但是这就是试试。无感方案需要添加3个电流采用放大器。还需要升级 mcu 要有足够的算力。 这些升级的成本反而远超一个编码器的成本。 |
不一定。低速可以用高频注入的方法实现,可以在不增加任何电路的情况下做到低速无感。同时MCU算力其实并不需要非常高。就miniFOC v2使用的CH32V203这颗MCU而言,做了定点计算优化之后的算法做一次闭环的计算耗时在4us左右,绰绰有余了。 |
