ABSTRACT

The development of technologies affects the demands of industries at all times. Automatic control plays a vital role in the advance of engineering and science. In today’s industries, control of DC motors has become a common practice. Therefore, implementation of DC motor controller is required. There are many types of controllers that can be used to implement the elegant and effective output. One of them is by using a PID controller. PID are designed to eliminate the need for continuous operator attention thus providing automatic control to the system. This paper is focused on implementing PI and PID controllers to control the speed of a DC motor. The DC motor was modeled mathematically and simulated using MATLAB/SIMULINK. The overall paper is divided into two parts. The first part is concerned with the simulation of the DC Motor using MATLAB SIMULINK while the second part dealt with the simulation of the DC motor and PI,PID controllers at different operating conditions. From the results obtained, it was shown that the due to inrush current at start-up, the armature current of the DC motor has high transient. Concluding, it was observed that the PID controlled DC motor showed significantly reduced overshoot, and increased settling time at various loads of when compared with the PI controlled DC motor.
