Hello,
I am new to motor controls. I am working through the Insta-Spin FOC labs. They are very nice and all the hardware and software is working very well. This is a great learning tool. I have question about Lab 5a. This lab gives a step by step analysis of the PI gains and how to determine them for your motor loop gain. I noticed in the block diagram in Lab 2a the output of the PI block goes to the INV park and then space vector modulator and then to the motor -the way I would expect. However in lab 5a, the output of the PI block produces a motor voltage and skips the SVM gain. Does anyone understand why the SVM gain is omitted? Is it not needed? I know in DC DCs and in sine wave inverters the inverter gain is required to determine the loop gain. Is this not true for SVM.
thanks,
Chuck
