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
