Project - Speed Control of a Direct Current (DC) motor

ans-

In this project,firstly dc motor create as shown in fig.

Propotional,integral,deravative(PID)block designed to gained knowledge, develop and test a controller to maintain a desired speed for the motor.

DC subsystem connected to PID block to maintained desired speed as itis.

After PID controller begin with Kp,Ki,Kd as 1.0,1.0 and 0 as we can adjust kp,ki,kd as 18.22,51.20,0.95.

subsystem of DC motor-

Discrete PID controller block parameter

adjust the graph by tuning

Taking step block as input the desired speed is 30:

Graph of desired speed and actual speed 

Graph of back emf,torque,armature current has same .

Taking step block as input the desired speed is 250

Graph of desired speed and actual speed 

Graph of back emf,torque,armature current has same .

From above two cases,we can show that  Plotting Remains same we change desired speed as 30 in case 1 and 230 in case 2 Hence, we maintain desired Speed For a Dc Motor.
