Other Parts Discussed in Thread: LAUNCHXL-F28069M, BOOSTXL-DRV8301, MOTORWARE, DRV8301, INSTASPINUNIVERSALGUI

LAUNCHXL-F28069M is now available for immediate shipment.

$25 LaunchPad with TWO sets of BoosterPack connectors
Dual encoder headers and isolated CAN
InstaSPIN-FOC and InstaSPIN-MOTION support (or use for non-InstaSPIN development as well)
MotorWare projects for both sets of BoosterPack BOOSTXL-DRV8301 connectors individually
- Future MotorWare release will include projects with the single LaunchPad controlling both motors (summer '15 release)
- Development Partners like The Mathworks/Embedded Target and Altair/VisSim are already demonstrating dual motor operation using their own software

Initial Position Detection using High Frequency Injection (IPD_HFI) Library

First release with initial example project on DRV8301 EVM (not BOOSTXL) using F2806x
Future releases for other inverter hardware and F2802x and F2805x
- You can port the projects yourself as well
New projects with write-ups in the Project & Labs User's Guide
- proj_lab20: example of slightly different CTRL code format, with PI controllers in CTRL and FOC/Transforms in mainISR
- proj_lab21: implementation of IPD_HFI with InstaSPIN-FOC (torque mode), including new AFSEL function to transition between IPD_HFI and FAST.
- future projects will include velocity control example
Notes for IPD_HFI
1. It is not "insta". It requires manual tuning (using a current probe is ideal) to select the proper values.
2. It will not work with all motors. A certain amount of saliency (based on the rotor construction) is required.
3. Please review the Projects thoroughly.

MotorWare Updated to version 1.01.00.14

Support for new LaunchPad
Support for new InstaSPIN-FOC based IPD_HFI projects (proj_lab20, proj_lab21; initially for DRV8301 EVM and F2806x)
Updated sw\drivers to align with additional driver work being done across TI MCU

There is also a minor update happening for INSTASPINUNIVERSALGUI to version to v104. That should be posted later today.

For the LAUNCHXL-F28069M you may notice that proj_lab02a has been removed for release _14 due to instability. We will add back in once fixed. This issue isn't appearing on ANY other inverter + controller combination that we can see.

The Mathworks has posted a very nice training video on how to run two motors using LAUNCHXL-F28069M and two BOOSTXL-DRV8301

Hi Chris, from Mathworks page linked i got this error:
The file you are trying to view is not in a published state.

agreed. I've sent a note to Mathworks to get this resolved.

Hi,
The link is back online and is permanent. The video is going through another round of reviews, but should show on the page within a week. The Simulink model can be downloaded on the page today.

Thanks,

Thanks guys, this is very exciting! So far I've been developing an inverter around the older form-factor (the DIMM module card), which worked nicely in the prototype stage - but this new LAUNCHXL module is priced rather aggressively, I'm considering to switch..
Also high frequency injection library? Can't wait to try and compare it on my InstaSPIN system :)

When do you expect to get a new IPD_HFI version with speed loop?
What do you think about sensorless traction control in a electric car with 8: 1 reduction? Could it be? Does it depend of rotor saliency?

Thanks

Javier

"When do you expect to get a new IPD_HFI version with speed loop?"
I'm hopeful this will be in MotorWare _15, target is July release.

"What do you think about sensorless traction control in a electric car with 8: 1 reduction? Could it be?"
Is there just a single propulsion motor, or are you trying to synchronize two motors? If needing to sync two then this will be VERY challenging for a sensorless application. If you have a single motor than this could be done.

"Does it depend of rotor saliency?"
The IPD_HFI technique does depend on motor saliency, especially for the tracking of the angle between zero speed and the transition to FAST. So there are some applications where a non-salient motor may work well enough for the initial angle and a lower-load start-up to FAST. But for heavy/dynamic load applications (like an e-bike) you really need to continuously track the rotor, and for this a highly salient motor design is required for IPD_HFI.

Hi there,
In the next release of MotorWare is it possible to replace the define for which header set to use (for LAUNCHXL-F28069M) with an user parameter? It would be easier to control two motors with the same board this way

ChrisClearman over 8 years ago in reply to Benjamin Hudson

TI__Guru** 118000 points

I don't think we will do that as too many things need to be decided before compile based on which set of headers you are using.

ChrisClearman over 8 years ago in reply to Benjamin Hudson

TI__Guru** 118000 points

We are looking at how we will do this when we show a 2 inverter control example. We thought this would work fine but are discussing further.

An important note, the .cmd files for F28027F and F28026F have an error. These are being updated for version 15 and are also posted on this thread:
