This paper presents a modeling method of a speed control for DC servo motor. This System is modeled by using the system level simulation program, Matlab/Simulink. The main purpose of this simulator is related to the development and validation of advanced control techniques applied to DC motors In Matlab/Simulink, a graphic user interface is supported, and system structures can be easily visualized. In the developed simulator, the subsystems of DC motor are implemented using three ways; modeling for the DC motor, PID auto-turning, stability. To simulate a speed control for DC motor in the simulator, the blocks or modules, which are elements of a control system, are simply connected by lines. The simulation results can be displayed using the built-in graphic functions in Matlab in Matlab or the scope; which is one of the block libraries in Simulink. The adoption of this simulator improves mpdularity, reusability and productivity in studying a Control system.
