DC Motor control with matlab help

[differentside]

hello, I need to design an electric engine start system with DC or BLDC motor to result more than 16Nm torque before reaching 2400 rpm. [im using matlab and simulink]
I've experienced designing simple pid controller but not getting the idea to start this project.
so these are some specs given to me....
- input= 28V DC, battery = 24V dc, max current = 500A
- the wire from battery to motor is AWG 1 (d, A, L, R/m given)

I guess i have to choose a specific motor for this modeling project and find the transfer function.
Than i don't have an idea about what controller I have to use and how to tune them.
Also, is there a way to see the graph of torque vs rpm in matlab?
I will be very appreciated if somebody can help me with this.
thank you so much !!!!

Why don´t you start with basics, like simple math?

mechanical power: 16Nm @ 2400 rpm = about 3500W (you need)
electrical power: 28V @ 500mA = 14W (available)

--> you can´t generate a mechanical power of 3500W with an electrical input of just 14W.
--> review your requirements
The electrical power needs to be higher that the mechanical power due to efficiency.

oops sorry the max curr is 500A not mA. and also I can put a battery with 24V DC!
