A Comparative Study of P-I, I-P, Fuzzy and Neuro-Fuzzy Controllers for Speed Control of DC Motor Drive
Creators
Description
This paper presents a comparative study of various
controllers for the speed control of DC motor. The most commonly
used controller for the speed control of dc motor is Proportional-
Integral (P-I) controller. However, the P-I controller has some
disadvantages such as: the high starting overshoot, sensitivity to
controller gains and sluggish response due to sudden disturbance. So,
the relatively new Integral-Proportional (I-P) controller is proposed to
overcome the disadvantages of the P-I controller. Further, two Fuzzy
logic based controllers namely; Fuzzy control and Neuro-fuzzy
control are proposed and the performance these controllers are
compared with both P-I and I-P controllers. Simulation results are
presented and analyzed for all the controllers. It is observed that
fuzzy logic based controllers give better responses than the traditional
P-I as well as I-P controller for the speed control of dc motor drives.
