Design of neuro-fuzzy controller for the speed control of a DC servo motor

Abstract

The authors have designed a neuro-fuzzy controller to improve some problems that occur when the nonlinear system is controlled by a fuzzy logic controller. Their model obtains fast-time response, maximized learning effect and shortened settling time. To prove the capability of the neuro-fuzzy controller designed in this paper, this neuro-fuzzy model is applied to a DC servomotor. As a result, this controller does not produce overshoot, which occurs in the PID controller, and also does not produce the steady state error of FLC. Also, it shortens the settling time by about 10%. In addition, the authors are aware that their model has only about 60% of the value of current peak of the PID controller.
