6.4 Torque Control, Speed Control, and Advanced Modulation Techniques

To implement more advanced modulation techniques such as torque control, speed control, and algorithms such as MTPA, Field-weakening, and PowerWarp (EPL) using the DRV8317HEVM InstaSPIN Universal GUI, please consult the MotorControl SDK InstaSPIN Lab Guide found in MotorControl SDK.

This document contains detailed lab overviews of how to implement each advanced modulation technique when using sensorless FOC to spin the BLDC motor in Code Composer Studio. In order to use the project with the GUI, the user must build and compile the project in CCS, and import the .out binary file for that project into the GUI properties through GUI Composer. More information can be found in the README when the GUI is first opened.
