Comparison of Proportional Integral Derivative Controllers (PID)
The components of a PID controller – Proportional (P), Integral (I), and Derivative (D) each have distinct characteristics and applications.

In this article, we will use the PWM output of the PID and show the difference in PID controller behavior between the two types of outputs.
A PID controller is used in automation processes to regulate or control the value of a process parameter such as temperature, level, etc.
Distinguishing Characteristics P-only Accelerates the response of controlled process Produces offset except for integrating (1/s) processes PI Eliminates offset Usually
