Control Engineering
Simply put, automatic control theory is about to control systems so that they behave as desired. Control Engineering is "The sience of automated systems". Automatic control Engineering is a broad and exciting area of technology with a long history. Already in the 1700s they used Centrifugalregulator to ensure that windmills spinning at constant speed and the same system was applied later for steam engines. Control systems have long been used in automatic pilots for airplanes and boats. Already in 1912 designed the American inventor Elmer A. Sperry, an autopilot for the aircraft.
