Fuzzy logic provides an accurate controller for controlling the systems when compared to the classical controllers such as a PID controller. In this work, a fuzzy logic controller (FLC) designed to control the position of a D.C. motor. The motor model is developed and transformed in subsystem by using the Matlab/ Simulink and its parameters taken from a datasheet for a real motor. The control signal adjusted in real time using proper fuzzy membership functions depending upon the armature voltage applied to the D.C. motor. Here tow inputs and one output are used. The fuzzy input variable (error) has seven membership functions, the fuzzy input variable (change of error) has five membership functions, and the fuzzy output variable represented by applied voltage has five membership functions. Important study parameters include input voltage of DC motor and its response for achieving accurate position and high efficiency of the motor. The results of the control achieved a suitable response for applications.
