DC-DC BUCK CONVERTER FOR DC MOTOR BASED ON HIERARCHICAL CONTROL

DC motors are widely used in systems with high control requirements. Thus, rolling mills, double-hulled tankers, and high-precision digital tools can be mentioned as examples of such systems. Generally, to control the step less velocity and smoothness, adjustment of the armature voltage of the motor is used; while, certainly, applying pulse width modulation (PWM) signals with respect to the motor input voltage is one of the methods most employed to drive a DC motor.
