Servo motors are used in many areas in these days like automation technology, robotics and camera auto focus and may other areas. Majority of these applications require precise motor control of servo ...

This paper presents the speed control of a separately excited DC motor (SEDC). Motor speed control is focused by controlling the field current. This method can be applied to achieve energy savings in ...

Abstract: Classical speed controller is challenged by nonlinear factors such as discontinuities in the stator iron cores, fluctuations in excitation current, and variations in the suspension air gap, ...
