As the general theory of feedback systems, control theory is useful wherever feedback occurs - thus control theory also has applications in life sciences, computer engineering, sociology and operation research. ==History== Although control systems of various types date back to antiquity, a more formal analysis of the field began with a dynamics analysis of the centrifugal governor, conducted by the physicist James Clerk Maxwell in 1868, entitled On Governors.

Control theory was further advanced by Edward Routh in 1874, Charles Sturm and in 1895, Adolf Hurwitz, who all contributed to the establishment of control stability criteria; and from 1922 onwards, the development of PID control theory by Nicolas Minorsky. Although a major application of mathematical control theory is in control systems engineering, which deals with the design of process control systems for industry, other applications range far beyond this.

Independently, Adolf Hurwitz analyzed system stability using differential equations in 1877, resulting in what is now known as the Routhâ€“Hurwitz theorem. A notable application of dynamic control was in the area of manned flight.

The Wright brothers made their first successful test flights on December 17, 1903 and were distinguished by their ability to control their flights for substantial periods (more so than the ability to produce lift from an airfoil, which was known).

Adaptive controls were applied for the first time in the aerospace industry in the 1950s, and have found particular success in that field. A [control system] is a type of control system in which a set of devices and governing software is arranged in a
