Design and real-time implementation of a fuzzy PI controller on a servo speed control application
Arijit Ghosh, Satyaki Sen, Chanchal Dey · 2015
Servo control systems are very popular in process automation. Towards achieving and maintaining the desired speed in close-loop application, fuzzy controllers are more competent in comparison with their conventional counterparts. Based on the prior knowledge, a rule-base is designed here comprising of forty-nine if-then rules using simple triangular membership functions. The non-linear behaviour of such servo systems can also be efficiently managed by proper designing of rule-base with appropriate choice of scaling factors. Superiority of the designed fuzzy PI controller is verified through simulation study on a servo speed control system and in addition it is successfully implemented in real-time on a hardware setup.
