I’m open to helpful ideas about this project. Thanks.

I will make a project using this engine 100:1 Micro Metal Gearmotor HPCB 12V with Extended Motor Shaft.

You should design an analog controller using op-amps. You can choose a PI, PD or PID type of

controller.

1.Design and draw the electro-mechanical structure of your car with a mass “MC” powered by an

electrical motor “m”.

2.Find an appropriate model (toy) car with a DC motor. Find the gear ratio, wheel radius and

circumference. Use an electronic scale to measure the amount of traction force of your car and

torque that your motor produce with respect to the armature current. Find the armature

resistance Ra. Find the stall torque Tstall and max speed ωno-load of your motor. Find “Motor Torque

Coefficient” Kt , of your motor. Draw “torque Tm“ versus “speed ωm“ graph of your motor.

- Find the transfer functions X(s) / Tm(s) and Tm(s) / Ea(s), where X(s) is the position of the car

The project conditions are as follows.
