Performance Analysis of Speed Control of PMDC Motor using Fuzzy Logic Controller

Abstract

In this study, performance analysis of speed control of PMDC (Permanent Magnet Direct Current) motor using fuzzy logic controller was realized in Matlab/SIMULINK environment. Firstly, the mathematical model was obtained using the mechanical and electrical values of electrical equivalent circuit of the DC motor. Then, the fuzzy logic and PI controller structures was designed. Different references speeds were applied to the systems controlled by the FL and the PI controller. Additionally, in this study, the effect of varying armature resistance of the PMDC motor on the controller structures used in simulations and on the speed of the PMDC motor was also investigated. Comparisons were made for both controllers considering the same conditions. According to the results obtained by using the data in this study, it is observed that the fuzzy logic controller has a better performance than the PI controller.
