Hello, I need to develop BLDC model with SVPWM and vector control using 3 pid loops (controling for position, speed and current). I've already built the model to controlling for speed but my PI controllers do not work well when I try to control speed. Can anyone explain me where I wrong? I have attached screenshot and my model which includes motor model, PID controller blocks, SVPWM generator and Park-Clarke transformations.
