Hi Guys,
I have a question about PMSM rotor postion test using the resolver sensor of the MTRCKTDPS5643L board.
frist:i wanna konw that the POS_SIN and POS_COS in fig1,response to Usin and Ucos in fig2.
figure1
figure2
The second:
There is a doubt that we identify the rotor postion using the method that mentioned in the file named AN1942 is or not.
The method in AN1942:
1、Trigonometric
2、 Angle Tracking Observer
Hi edenli,
Q1: first, i wanna know that the POS_SIN and POS_COS in fig1,response to Usin and Ucos in fig2.
A1: Yes, they are. Please keep in mind that there are 2 revolvers interfaces on the board - so you need to pay attention which one you choose.
Q2: the second, there is a doubt that we identify the rotor position using the method that mentioned in the file named AN1942 is or not.
A2: The method used in the souce files if based on Angle Tracking Observer. You can check POSPE_GetPositionElRes()
Hope this helps!
Daniel
