I am now designing a motor control system for PMSM and I am at the very beginning steps of designing current loop. I am struggling with decide the parameter of 3 phase PLL block which i have never seen before.

For PI controllers, i use pole zero cancellation method to decide their parameters, which is from https://e2e.ti.com/blogs_/b/motordrivecontrol/archive/2015/07/20/teaching-your-pi-controller-to-behave-part-ii

Hi,

Your question, as i inderstand is related to 3-phase PLL in simulink, and i hope if u fix the frequency in the PLL block it should work. If you want to design the PLL by using transfer function block, you may proceed through a second order filter.

Hope it should work.

Thanks
