Control For Position DC motor

Abstract

    There are several industrial  ,automatic ,and other  processes that require the control of angular position of  a motor (or translation position) the stepper motor achieve this purpose but the stepper motor lack the advantage of controlling the angular position at wide range ofspeeds; this aim is achieved by using dc motor which allow us to control the position at a wider range of speeds in both reverse and forward direction.Position control systems are an important component of many industrial products . Examples are found in disc drives ,automotive products ,robotics ,process control and many others
