PID parameters significance mentioned in User guide and how to calculate them ?

[pratibhasurabhi]

I am using MagniV development board for for BLDC control .... I have also took reference from NXP code for speed and current loop control with PI control ..... for PI control loop parameters calculations are done using freemaster tool....Is there any such tool for PID loop parameter calculation ? Also please define significance of PID parameters used in NXP PID function mentioned in user guide that came with code .

Hello,

We use PI controllers in the structures of our motor control examples on the web. As you write, Mcat helps with the calculation of parameters for the PI controllers used (for PMSM in the cascade control structure for BLDC in the structure for sixstep). At the moment we do not have an example on the web that would use a structure with a PID controller or a tool that would help to set it, but of course, our AMCLIB library also offers this function as a building block for customer control structures.

I hope it helps.

Best regards,

Diana
