After a few years, control engineers removed the error of steady-state that is found within proportional controllers through retuning the end to some false value until the error wasn’t zero. After that, TIC (Taylor Instrumental Company) was implemented a former pneumatic controller with completely tunable in the year1933.
The history of the PID controller is, In the year 1911, the first PID controller was developed by Elmer Sperry.
