Fuzzy Logic Speed Control of a DC Motor : Control has proven for a long time to be good enough to handle control tasks on system control however, his implementation relies on an exact mathematical model of the plan to be controller and not simple mathematical operations. The fuzzy logic, unlike conventional logic system, is able to model inaccurate or imprecise models.The fuzzy logic approach offers a simpler, quicker and more reliable solution that is clear advantages over conventional techniques. Therefore take Matlab for develop of the control system that append with fuzzy logic is incoming for modem control and the advantages in fuzzy control are more robust control method than usual conventional control to variation of system parameter.
