    ABSTRACT Working with high order transfer function needs a lot of work. Transfer functions of high order may be approximate as low order transfer function with time delay. This done by First Order Plus Dead lime (l'()l’I)'l‘)_ Second ()rder Plus Dead Time (SOPDT) and Skogestad. The main objective ofthis research is to approximate the higher order transfer function to first and second order transfer function using the three methods. Then compare the result with the original plant transfer function so as to test the dependency of these methods . DC motor speed transfer function was taken as model to verify the result.
