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)

(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
