What it does

  • Covers 19 control modes, from open-loop V/F and I/F through encoder, Hall-sensor and sensorless operation.
  • Sensorless estimation uses HFI high-frequency injection plus SMO and NLFO flux observers, with switching between them.
  • Includes PID, LADRC, SMC and STA controllers, plus MTPA, field weakening, dead-time compensation and cogging compensation.
  • Offers motor parameter identification, pole polarity identification and a JustFloat serial protocol for debugging.
  • Configuration is done through user header files such as UserData_Config.h, with the run mode selected by a macro.
