Phase current PID

info

Next variables are located in the folder /driver/pid_iq resp. /driver/pid_id.

info

The PID is abbreviation of 'Proportional-Integral-Derivative' closed loop regulation.

In the current control loop, only the P and I terms are used.

VECTOR​

  • Q axis -> Torque-generating axis
  • D axis -> Flux-generating axis

BLDC​

  • BLDC algorithm uses only parameters from pid_iq
  • Parameters from pid_id are not used during motor control. It is presented only for the embedded identification procedures (identlin, identrun, ...). Therefore, changing its parameter will not affect motor control performance.

Parameters​

Parameters and settings for both pid_iq and pid_id have the same meaning.

P [-]​

Proportional term in the PID loop.

I [-]​

Integral term in the PID loop.
