Abstract:
DC Motors are widely used in industries for various purposes. Many
situations demand changes in the speed of the DC Motor, and this makes
necessity to develop a method to effectively control the speed of DC motor.
There are conventional and digital controller types, Proportional Integral (PI),
Proportional Derivative (PD), Proportional Integral Derivative (PID) and
Fuzzy Logic Controller (FLC). The Fuzzy Logic Controller is used to improve
the performance of each controller (PI, PD and PID) used to control speed of
the DC motor. In this project PI, PD and PID (with and without Fuzzy Logic
Controller) was modelled and simulated in MATLAB SIMULINK
environment to control speed of the DC Motor. Aforementioned Controllers
were analyzed and evaluated on four terms overshoot, rise time, steady state
error and settling time, the purpose of the evaluation to find the best
performance to control the speed of DC motor. As a result of this, the Fuzzy
PID is the best controller because its improved performance when compared
with others controllers.
