#define OVM_VREF_MODE2_START ((int32_t)31186)The ratio between these two value is not sqrt(3)/2. What is the voltage unit used in these calculation? Or when a have a Valpha equal to 32767, what is the tru...
How to calculate the gain parameter of PI controller in PLL generated by workbench? After doing lots of researching, I found two magic numbers: kp corresponds to 532 and ki corresponds to 1506742, how do I get them?
Found something interesting:the PI controller and FF think the voltage reference is Vbus/2,the PWMC_SetPhaseVoltagefunction thinks it's Vbus/sqrt(3),PWMC_SetPhaseVoltage_OVM thinks it's 2Vbus/3,circle limit in OVM mode thinks it's -- 2Vbus/pi, right?
Also, the document "A priori determination of flux and torque current PI gains" says that the PI module uses a voltage factor of VBusDC/2^16, is this correct?Seems like it should be 3VBusDC/2^16.
If you can understand the vector dot product, then it's easy to understand: the value of Y is equivalent to the dot product of the vector (Vα,Vβ) and the vector (√3/2,1/2), which points in the direction of 30°, i.e. if Y is greater than 0, the angle ...
