This paper presents the application of fuzzy logic to the speed control of DC motor as a way of overcoming the shortcomings of conventional controllers. One of the advantages of fuzzy logic control is that it can be successfully applied to control nonlinear and complex systems using an operator experience or control engineering knowledge without any mathematical model of the plant. A model of separately excited dc motor was created together with the Fuzzy Logic Controller (FLC) using a technical computing software (MATLAB/SIMULINK). The performance of the fuzzy logic controller was studied extensively by simulation to validate the theoretical concept. The simulation study indicates clearly the excellent performance of FLC, because it is adaptive in nature.
