This paper aims to add a controller to the exiting milling machining transfer function according to some design requirements, while establishing a control system based on Simulink simulation, the system corrected through Mat lab simulation. This experiment uses advanced correction methods to improve the system performance, observe its step and ramp response to determine the parameters needs be used to describe the corrector. The basic idea of this correction is use using the bodes diagrams and root locus method to check the system is stable or not through the static gain, root locus gain will be used to improve the system through the phase lead and phase lag methods, simulation analysis of the steady state error of the closed loop transfer function ramp input and the analyses of the step response of the open loop transfer function of the system overshoot will be used as good indicator to obtain the design requirements.
