【概要描述】In 1945, the American mathematician Wiener, N. extended the concept of feedback to all control systems. After the 1950s, there have been many new developments in classical control theory. . The methods of classical control theory can basically meet the needs of military technology in World War II and the needs of post-war industrial development. But by the end of the 1950s, it was discovered that the generalization of the methods of classical control theory to multivariable systems would lead to wrong conclusions. The classical control theory approach has its limitations.

The concept of automation is a dynamic development process.

The concept of automation is a dynamic development process. In the past, people's understanding of automation or the functional goal of automation was to replace manual operations with mechanical actions to automatically complete specific tasks. This is essentially the idea of automation replacing human manual labor. Later, with the development of electronics and information technology, especially with the emergence and wide application of computers, the concept of automation has been expanded to replace not only human physical labor but also or assist mental labor with machines (including computers) to automatically Complete specific assignments.

The late 1950s has been the period of comprehensive automation.

The late 1950s has been the period of comprehensive automation. During this period, space technology has developed rapidly, and it is urgent to solve the optimal control problem of multi-variable systems. Thus was born the modern control theory. The formation and development of modern control theory have laid a theoretical foundation for comprehensive automation. At the same time, new breakthroughs have been made in microelectronics technology. Transistor computers appeared in 1958, integrated circuit computers appeared in 1965, and single-chip microprocessors appeared in 1971. The emergence of microprocessors has had a significant impact on control technology, and control engineers can easily use microprocessors to implement various complex controls, making comprehensive automation a reality. "Automation" was proposed by American D.S.Harder in 1936. He believed that in a production process, the transfer of parts between machines without human handling is "automation".

The electronic digital computer invented in the 1940s

The electronic digital computer invented in the 1940s opened a new era of digital program control. Although it was still limited to automatic calculation at that time, the successful manufacture of ENIAC and EDVAC opened a new era of electronic digital program control. The invention of electronic digital computer laid the foundation for the widespread application of program control and logic control in control systems in the 1960s and 1970s, as well as the extensive application of electronic digital computers to directly control the production process.
