History of control system

1) B.C.200 – Float regulator mechanism (Greece)

2) B.C.50 – Water clock (Middle east)

3) 1600 – First feedback system (temperature regulator, Cornelis Drebble, Holland)

4) Sir Isaac Newton (1642 – 1727) – Mathematical modeling

5) Brook Taylor (1685 – 1731) – Taylor series

6) 1700 – Pressure regulator for steam boiler (Dennis Papin)

Pressure build up (temp. goes up) ( open the damper for release of hot air.

Temp. sensor is used to measure the pressure of hot air.

7) Pierse Simon Laplace (1749 – 1827) – Laplace Transform

8) 1769 – First automatic controller (Flyball governer, James Watt)

9) 1765 – First level regulator system (I. Polzunov, Soviet Union)

10) Edward John Routh (1831 – 1907) – Routh criterion

11) Oliver Heaviside (1859 – 1925) – mathematical analysis

12) 1868 – Mathematical theory for control system

(J.C. Maxwell)

13) 1890’ - Stability theory (Liapunov, Soviet Union)

14) 1914 – Lawrence Sperry demonstrated gyroscope (airplane autopilot) for planes that had been developed by his father Elmer Sperry.

15) 1930’ - Electronic feedback amplifier

(Nyquist, Bode, Black ; Bell Telephone Lab)

• Harry Nyquist (1889 – 1976) – Nyquist criterion

• Harold Black (1898 – 1981) – Negative feedback amp

• Hendrik Bode (1905 – 1982) – Bode diagram

16) WWII period – Automatic airplane pilot

Gun-positioning system, radar

Antenna control system

Military systems

17) Post War – Frequency domain analysis

Laplace transform method

18) John Von Neumann (1903 – 1957) – Basic operation of digital computer

19) 1941 – Albert C. Hall recognized the harmful effects of ignoring noise in control system design, while designing an airborne radar.

20) 1943 – David B. Parkinson (Bell Telephone Laboratories) designs anti-aircraft gun controller.

21) 1950’ – Root locus method

Computer age open (digital control)

Space age (Sputnik, Soviet Union)

Maximum principle (Pontryagin)

Optimal control

Adaptive control system (Draper)

22) 1960’ – Dynamic programming (Bellman)

State space method

23) 1970’ – Microprocessor based control system

Digital control system

24) 1976 – First Space Shuttle

25) 1961 – First mass-produced embedded system was created for Minuteman 1 ballistic missile.

26) 1968 – Embedded Systems are released to the automotive industry after the first use of an electronic fuel injection system by Volkswagen.

27) 1969 – First microprocessor invented by Ted Hoff.

28) 1980 – Neural network

AI

Fuzzy control

Predictive control

Doyle & stein : LQG / LTR
