A theory related on DC Motor Speed Controller includes the speed control application circuits are described in thegenerating pwm circuit schematicfollowing document. In order to take a signal representing the demanded speed, and to drive a motor at that speed, a motor speed controller is needed.

What you will find in the depth of the document are sections such as Theory of DC motor speed control, The action of inductive loads, and inductors, PWM frequency, Choosing a frequency based on motor characteristics, Speed control circuits, Regenerative Braking Circuit, Reversing DC Motor, The Full Bridge Circuit, Generating PWM signals (using 74HC14, 74HC163, LM324), Current limiting circuit, and Feedback Speed Control.
