Tune Field-Oriented Controllers Using SYSTUNE

This example shows how to use the systune command to tune Field-Oriented Control

(FOC) for a permanent magnet synchronous machine (PMSM) based on frequency

response estimation (FRE) result.

Introduction of Field-Oriented Control

In this example, field-oriented control (FOC) for a permanent magnet synchronous

machine (PMSM) is modeled in Simulink® using Simscape™ Electrical™ components.

mdl = 'scdfocmotorSystune';

open_system(mdl)

SignalBuilderPath = [mdl,'/System_Inputs/Signal_Builder_Experiments'];

Field-oriented control controls 3-phase stator currents as a vector. FOC is based on

projections, which transform a 3-phase time-dependent and speed-dependent system into

a two-coordinate time-invariant system. These transformations are the Clarke

Transformation, Park Transformation, and their respective inverse transforms. These

transformations are implemented as blocks within the Controller_Algorithm subsystem.
