PID and DC motor

1. How to Tune a PID Controller

2. DC motor PID speed control

Learn how to control the speed of a DC motor with an encoder using a PID controller. In this video, there are several important steps in this process:

0. Hardware

1. Velocity measurements

2. Measurement filtering

3. PI control

4. Variations

3. How to control a DC motor with an encoder

In this video, Curio Res illustrates how an encoder works, and then use a PID control algorithm to control the motor position. All of the steps are included so that you will be easily able to make the system yourself.

What Is PID?

From Wikipedia: "A PID controller calculates an 'error' value as the difference between a measured [Input] and a desired setpoint. The controller attempts to minimize the error by adjusting [an Output]."

So, you tell the PID what to measure (the "Input",) Where you want that measurement to be (the "Setpoint",) and the variable to adjust that can make that happen (the "Output".) The PID then adjusts the output trying to make the input equal the setpoint.

For reference, in a car, the Input, Setpoint, and Output would be the speed, desired speed, and gas pedal angle respectively.
