Intelligent single-axis control for brushless dc motors is the driving force behind the MC3110 motor controller. The device operates in three modes: internal velocity profile mode, velocity mode ...

This paper presents a DC motor speed controlling technique under varying load condition. The linear system model of separately excited DC motor with Torque-variation is designed using PID controller.

Add to this the excess induced current that is generated when a spinning motor is shut off and you’re going to need a control system that can handle these dangers. Enter the h-bridge motor driver.
