First of all, Ud and Uq from the current loop may cause the voltage vector to be over-modulated. To prevent this from happening, ST has provided a calculation method with a clear physical meaning, which is to pull the vector back in proportion, as shown in the following figure: Then, in the specific implementation, the ST algorithm is as follows: Question: How is the circle_limit_table in the algorithm created? ? How is START_INDEX determined? ? [Note]: Below are two tables with modulation ratios of 0.89 and 0.91
