Simple data test incorporating foc-related libraries

This example runs verifies various transforms libraries used in motor-control application, specifically as a building block of Field of Control (FOC) motor design.

It demonstrates how to run clarke, park, inverse park transform and space-vector generation (svgen). This test trys to mimic a conventional workflow of passing current values into clarke transform, then park, then inverse park (PI controllers are neglected here but should exist for both open and close-loop design) and finally passing to svgen to generate the three-phase ABC value.

The test used an aribitary phasor angle that feeds into park/ipark, as opposed to an angle generation module required by an actual FOC design.

The test vector then compares the PARK, SVGEN results to ensure the integraty of the library.

Steps to Run the Example

• When using CCS projects to build, import the CCS project for the required combination and build it using the CCS project menu (see Using SDK with CCS Projects ).
• When using makefiles to build, note the required combination and build using make command (see Using SDK with Makefiles ).
• Launch a CCS debug session and run the executable, see CCS Launch, Load and Run
