This paper discusses DC motor control MATLAB simulation of the role and its strengths, then discussed and adopted the system software design, implementation of the DC motor using matlab / simulink as a simulation tool for the establishment of a mathematical model DC, Matlab software used in dynamic simulation tool Simulink, through examples of real-time simulation. Implementation of man-made machinery, this was followed by a DC motor on the open-loop speed control system simulation and speed closed-loop control of the DC converter system simulation.
