Part Number: TMS320F28377D
Other Parts Discussed in Thread: CONTROLSUITE
Hi team:
I was debugging the LEVEL 4 routine, and met with some problems:
1, In my current system, au6802 is used as a comparison. At different speeds, there is a big gap between the angle estimated by SMO and the angle extracted by au6802, which is close to 180 degrees. Why?
2, I want to run the speed mode. The speed calculation uses the real position calculation of AU6802. Park and I-Park use SMO estimation angles, Sometimes it goes well, sometimes it doesn't.
Because the motor position is random, how can we use SMO to estimate the angle to make Park and I-Park work normally when starting?
Best regards
