Abstract:
At the present time, Direct Current (DC) motors have been widely used in
many industrial applications. The main reason for their popularity is the
ability to control their torque and flux easily and independently. Therefore,
the control of the speed of a DC motor is an important issue and has been
studied since the early decades in the last century. The most commonly used
controller for the speed control of DC motors is conventional Proportional–
Integral (PI) controller. In spite of the major features of the conventional PI
controller, it has some disadvantages such as the high starting overshoot in
speed, the sensitivity to controller gains and sluggish response due to sudden
disturbance. To overcome these disadvantages, replacement of PI controller
by Integral plus Proportional (IP) controller is proposed in this project.
Performance of two controllers has been verified through simulation results
using MATLAB/SIMULINK software. According to the simulation results,
IP controller creates better performance in terms of overshoot, settling time,
and steady state error compared to conventional PI controller. This shows the
superiority of IP controller over conventional PI controller.
