Transfer function for varying inertia of load

Hello Ti  team,

I have one question related to setting motor Transfer function for varying inertia of load.

Can you suggest how to handle this case :--
1> Suppose i have a E-Rikshaw which is using BLDC motor to run the vehicle. Now in this vehicle there can be 2/3/4 person sitting at a time when it starts so Inertia is different for each case when motor starts ? So how to handle this type of case ?
2> Or washing machine with diffrent amount of load at each time it starts. so Inertia is different for each case ? So how to handle this type of case ?

So if load is varying & inertia is different every times when motor starts with varying amount of load then this will spoil my PI loop of velocity & current . How you handles this type of case ?


Regards,
Dinesh
