Tool/software:

How to find Kp, Ki and flux with the help of Rs, Ld and Lq of a PMSM motor. What is the realtion for finding flux without using any nameplate data, as I don't have the nameplate and only use the existing data. If there's any control algorithm to find it, please mention that too.

If you are using the sensorless-FOC with FAST example, the algorithm can identify the motor parameters, Rs, Ls and Flux.

You may refer to the lab for the C2000 devices in motor control SDK. The universal motor control lab is available in the current MCSDK, which can support a set of hardware kits and control algorithms for BLDC/PMSM drive. The kits include LAUNCHXL-F280025C, LAUNCHXL-F280039C, LAUNCHXL-F2800137 with DRV8316REVM inverter board for low voltage motor. The control algorithms include sensorless InstaSPIN-FOC with FAST, Sensorless-FOC with eSMO, Sensored-FOC with incremental encoder, Sensored-FOC with hall sensor. You can refer to the device peripherals (ePWM, ADC, eQEP, or eCAP) configuration for motor control with the other C2000 devices including F2838x.
