The 1940s and 1950s were the period of partial automation

The 1940s and 1950s were the period of partial automation. The classical control theory formed during the Second World War played an important role in promoting the development of partial automation after the war. In the process of the problem, the classical control theory was formed, various precise automatic adjustment devices were designed, and a new scientific field of system and control was created. This new discipline was called Servo Mechanism Theory in the United States at that time, and Autotuning Theory in the Soviet Union, mainly to solve the single-variable control problem. The name Classical Control Theory was proposed in 1960 at the first National Joint Conference on Automatic Control. After 1945, due to the lifting of the wartime publishing ban, there appeared works that systematically expounded the classical control theory.

The application of automatic regulators marks the entry into a new historical period of automation technology. After entering the 20th century, various automatic adjustment devices have been widely used in industrial production, which has promoted the analysis and synthesis of adjustment systems. Although the structure of feedback control has been widely used in automatic regulators during this period, the theoretical study of the principle of feedback control began in the 1920s. In 1833, British mathematician C. Babbage first proposed the principle of program control when designing an analytical engine. In 1939, the world's first professional research institutions for systems and control were established, which made theoretical and organizational preparations for the formation of classical control theory and the development of local automation in the 1940s.

In the 1970s, the objects of automation became large-scale and complex engineering and non-engineering systems

In the 1970s, the objects of automation became large-scale and complex engineering and non-engineering systems, involving many problems that were difficult to solve with modern control theory. The research on these problems has promoted the innovation of the theory, method and means of automation, so the system control of large systems and the intelligent control of complex systems have emerged, and advanced technologies that comprehensively utilize the achievements of computers, communication technology, systems engineering and artificial intelligence have emerged. Automation systems, such as flexible manufacturing systems, office automation, intelligent robots, expert systems, decision support systems, computer integrated manufacturing systems, etc.
