The aim of this task is to design a PID controller for a DC motor modelled in Simulink (or Octave, Octave Forge). Create a closed-loop system by using a controller block, then tune the gains of PID controller. What is the purpose of designing a PID controller for a DC motor?
1) To improve the speed control of the DC motor
2) To reduce the power consumption of the DC motor
3) To increase the torque output of the DC motor
4) To prevent overheating of the DC motor
