In 1946, D.S., a mechanical engineer at Ford Motor Co, first proposed the word “KAI AUTOMATION”,
It is used to describe the process of automatic transmission and processing. In 50s, with the development of automatic regulator and classical control theory, KAI AUTOMATION entered into the stage of local KAI AUTOMATION based on single variable automatic control system. In 60s, with the application of modern control theory and computer automatic control, combined with information processing, make KAI AUTOMATION into integrated KAI AUTOMATION stage optimal control and management of the production process.
In 70s, the KAI AUTOMATION of the object into a large-scale, complex engineering and non engineering systems, involving many modern control theory is difficult to solve the problem. The study of these problems, promote the theory, methods and means of KAI AUTOMATION reform, so there is a large complex system and intelligent control system of the control system, the advanced KAI AUTOMATION system by using computer, communication technology, system engineering and artificial intelligence achievements, such as flexible manufacturing systems, office KAI AUTOMATION, intelligent robots, expert system, decision support system, computer integrated manufacturing system.
The emergence and application of automatic devices in eighteenth Century. KAI AUTOMATION technology was formed in the late eighteenth Century to 1930s. 1788 British mechanic
J. Watt invented the centrifugal governor (also known as the fly ball governor), and it is connected with the steam engine valve, forming a closed loop automatic control system of steam engine speed. The invention of Watt created a new era in the application of modern automatic control devices, which had an important influence on the development of the first industrial revolution and later control theory. People began to use automatic control device to deal with the control problems in industrial production. These regulators are devices that track a given value, keeping some physical quantities near a given value. The application of automatic regulator marks the new historical period of KAI AUTOMATION technology. After entering in twentieth Century, a variety of automatic adjustment devices are widely used in industrial production. Although the feedback control structure has been widely used in the automatic control system in this period, the principle of feedback control is studied in 1920s. In 1833 the British mathematician C. Babbage in the design of aircraft first proposed the principle of process control. In 1940s, the world’s first professional institute of systems and control was established, making a theoretical and organizational preparation for the formation of classical control theory and the development of local KAI AUTOMATION in the 1939.
Twentieth Century 40 ~ 50s is part of the KAI AUTOMATION of the period of the Second World War, the formation of the classical control theory
On the development of local KAI AUTOMATION after the war played an important role in promoting. In the course of the problem, the classical control theory has been formed, and all kinds of precise automatic control devices have been designed. This new discipline was then referred to in the United States as the servo theory, in the Soviet Union called the automatic adjustment theory, mainly to solve the problem of single variable control. The name of classical control theory was presented in 1960 at the first United States joint automatic control conference. Since 1945, due to the release of the wartime publication ban, a systematic exposition of classical control theory. In 1945, American mathematician Weiner, N. extended the concept of feedback to all control systems. After 50s, the classical control theory has many new developments.. The method of classical control theory can basically meet the needs of military technology in the Second World War and the needs of post-war industrial development. But by the end of the 50s, it was found that the classical control theory can be applied to multivariable systems. The classical control theory has its limitations.
The invention of the electronic digital computer in 1940s ushered in a new era of digital program control, though it was still confined to the automatic calculation, but the manufacture of ENIAC and EDVAC’s success, ushered in a new era of electronic digital program control. The invention of the electronic digital computer was used in the control system from 60 to 70s, which laid the foundation for the application of the program control and logic control and the wide application of the electronic digital computer to control the production process.
Since the end of the 1950s, it has been a period of integrated KAI AUTOMATION, the space technology developed rapidly in this period, so it is urgent to solve the optimal control problem of multivariable system. Modern control theory was born. The formation and development of modern control theory has laid a theoretical foundation for integrated KAI AUTOMATION. At the same time microelectronics technology has a new breakthrough. Transistor computers appeared in 1958, in 1965 the emergence of integrated circuit computer, in 1971, a single-chip microprocessor. The emergence of the microprocessor has a significant impact on the control technology, the control engineer can easily use the microprocessor to achieve a variety of complex control, so that integrated KAI AUTOMATION become a reality. “KAI AUTOMATION” (KAI AUTOMATION) was proposed by the American D.S.Harder in 1936, he thought that in a production process, the transfer between parts of the machine without the need to move is “KAI AUTOMATION”.
