Henry Ford’ s mechanized assembly line for automobile(汽车) production in 1913 Historical Review H.W.Bode and H.Nyquist developed the analysis of feedback amplifiers at Bell Telephone Lab from the late1920s to the early 1930s (Frequency response methods) A large impetus to the theory and practice of automatic control occurred during World War II (auto-pilots, gun-positioning systems, radar antenna control system) Historical Review The first Numerical control machine tool was developed in MIT in 1952 In 1948, Walter R. Evans developed the root-locus methods The first industrial robot in 1954 Colombia Space shuttle was launched successfully for the first time in 1981 Historical Review Application of Control Systems 装配机器人 汽车自动焊接生产线 Application of Control Systems 自动立体仓库 Application of Control Systems Injection Molding Machine Automotive delivery vehicle Application of Control Systems Robot football match 月球车 Example of Control System Fig 1.2 system representation of temperature control Fig1.1 Water temperature control system Example of Control System Fig 1.3 automatic water temperature control system Fig 1.4 Block diagram of automatic temperature control system Design examples Problem Many modern devices use a turntable to rotate a disk at a constant speed. Our goal is to design a system for turntable(转盘) speed control that will ensure that the actual speed of rotation within a specified percentage of the desired speed. Design examples Block diagram Open-loop control of the speed of a turntable Design examples Closed-loop control of the speed of a turntable Block diagram References (参考教材） Richard C.Dorf and Robert H.Bishop.
