The drive motor of the electric steering unit uses a motor position sensor to perform current control. The accuracy of the motor position sensor affects current control. This further affects the torque ripple performance and steering of the vehicle. There are many types of motor position sensors used in electric steering systems, but MR sensors are mainly used in Korea. MR sensors have several advantages, but their own characteristics reveal the primary and secondary error components. To solve this problem, DFT was used to identify the corresponding components. And by compensating for this, we were able to check the data that the primary and secondary error components were offset through simulation. |
