Position control of DC servo drive using fuzzy logic controller

Abstract

This paper presents the position control scheme of DC servo motor drive. The fuzzy PI controller is developed for controlling the position of DC servo motor drive. The DC servo motors are highly preferred because of high power rating and speed of the motor. The proposed technique is a closed loop real time control scheme where the position control is obtained through position sensor, it is coupled with the motor shaft for provide a feedback position signal. The position control scheme of DC servo motor drive incorporating the fuzzy logic control which is experimentally implemented using a digital signal peripheral interface controller dspic 30F2010. The performances of the proposed fuzzy logic controller based DC servo motor drive were investigated and it is compared with conventional PI controller based drive. The simulated and experimental results of conventional and fuzzy controller is compared and results illustrates that the FLC gives better dynamic performance also it is more robust for industrial position control drive applications.
