Field-Oriented Control: Designing the Control Algorithm
This second video in the series shows how to develop a field-oriented control (FOC) algorithm with maximum torque per amp (MTPA) and field-weakening control. Using automatic tuning, learn how to compute initial PI controller gains for speed and current loops based on motor and inverter parameters measured in the previous video. Provided scripts help analyze current loop dynamics in time- and frequency-domains by computing and plotting the root locus, Bode diagram, and step response of the current loop using Control System Toolbox™.
