DC motor with PID

I'm trying to model a dc motor for an hev vehicle. My aim is to let the motor produce a target torque. I get the reference current with I=T/K then I compare this value to the current generated by the motor and I regulate armaturevoltage with a PID.
1) I get very high voltage values. It seems to me they are too high. Don't know if they are realistic.
2) I'd like to connect the motor to a simplified battery model. I don't have idea how to do it. Should I regulate the motor voltage so that it is equal to battery one?
I don't want to use Simscape.

1. When you say you get very high voltage values, do you mean the output of the controller outputs very high voltages? If this is the case, it is likely that your gains for the PID controller are poorly designed.
2. If your torque is proportional to current, you then would want your control loop to track some reference current with your input to the circuit a voltage or pwm signal.

Assalam-u-alaikum every one .I want to make a simulink project to control DC motor using PID controller, i am new in this field kindly some one guide me how can i precede step by step,Thank you .
