2.4.5 Step 4 Close the Speed and Current Loop

Objectives learned in this build level:

  • Evaluate the complete motor drive with incremental encoder-based field-oriented control (FOC).

In this build level, the outer speed loop is closed with the inner current loop. The rotor angle is measured from an incremental encoder connected to the QEP.
