ANFIS based speed control of DC motor

Abstract

This paper presents comparative analysis of different controller configuration for speed control of separately excited DC motor. The main aim of this paper is to obtain optimize speed characteristics of DC motor drive by minimizing transient response specification such as rise time, settling time and overshoot. The speed control of DC motor is done using PID, Fuzzy and ANFIS controller Configuration. PID controller tuning parameters are obtained using Ziegler Nicholas (ZN) and Modified Ziegler Nicholas (MZN) method. This PID configuration is used as a reference to develop Fuzzy and Anfis structure. In this study, transfer function based model of DC motor is developed with defined parameters which is then integrated with different controller configuration. Finally, the developed system is tested for number of simulation runs and comparative analysis shows that ANFIS provide superior features including easy implementation, good computational efficiency, and stable convergence characteristic and this has validated the robustness of the ANFIS scheme.
