![]() ![]() ![]() In 1942, Ziegler & Nichols have introduced tuning rules to discover and set the suitable parameters of PID controllers by the engineers. ![]() After that, in the year 1940, the first pneumatic PID controller was developed through a derivative action to reduce overshooting problems. This retuning included the error which is known as the proportional-Integral controller. 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. ![]()
