PID control at small PWM values for a DC motor
$begingroup$ Thanks for the paper, it deserves to be read carefully (especially the PWM part, which I'm already using but might need improvement). I'd slightly disagree about the backlash, because the encoder is attached to the motor shaft before the gears; on the other hand, the motor seems to have six windings while the optical …

motor
Your DC motor probably won't need any filters because its inertia will serve this purpose as long as the pwm frequency is high enough (some kHz should be sufficient). The motor eventually will produce some undesirable noise, in that case you might want to add a capacitor for smoothening.

How are DC motors controlled?
How do brushless DC motors work? The need for a drive circuit explained? ... Linear or PWM control can be used to vary the motor drive voltage. PWM control has come to predominate in recent years due to its superior efficiency. PWM control varies the voltage by turning a semiconductor switch on and off at high speed in such a way that …

555 Timer PWM DC Motor Speed Controller
The output of the IC needs to be connected to the base of the transistor through a resistor, and in my case I used 1k resistor. For preventing any voltage spikes produced by the motor we need to use a flyback diode which is connected in parallel with the motor. Designing a PCB for the PWM DC Motor Speed Controller

Pulse Width Modulation Used for Motor Control
Small DC motors ideal for use in applications were speed control is required such as in small toys, models, robots and other such electronics circuits. A DC motor consist basically of two parts, the stationary body of the motor called the "Stator" and the inner part which rotates producing the movement called the "Rotor".

why do I need a pwm and H bridge, after a PID controller to feed a dc
A motor may require 100V to get to the speed you want and many amperes to get the torque you need. To do that efficiently you need a PWM switching stage. Depending on the type of motor you may need commutation logic to keep the field in the right spot too.
