Future plans
The inverter has reached a stable and usable state as of today. This is the result of 7 design iterations. Still though, there is much room for improvement:
- Implement advanced motor control algorithms (DTC or FOC)
- Implement motor autotuning
- Resolver support to run PMSM - done!
- Integrate battery charging into the inverter - done!
- Integrate vehicle interfacing (e.g. rev counter)
- Integrate battery monitoring and SoC estimation
- Offer more communication (CAN, USB) - CAN done!
- Support synchronous motors - done! But some more testing needed
FOC will no longer be implemented because it offers no advantage when using a pulse encoder. Thus autotuning is not needed.
Battery monitoring should be done by a BMS instead of the inverter.
