Automation Automation overview of the machine or device in the absence of intervention procedures or instructions required automatic operation or control of the process, its objective is "steady, accurate, quick." Automation technology is widely used in industry, agriculture, military, scientific research, transportation, business, health, services, and the family. Not only can automated technology from heavy manual labor, part of the mental and the poor and dangerous working environment freed, but also to expand people's organ function, significantly raising labor productivity, and advancing human understanding of the world and the ability to change the world . Therefore, the automation of industrial, agricultural, national defense and science and technology an important condition for the modernization and significant signs. The development of automation in 1946, the United States Ford mechanical engineer DS Hudson was first put forward the "automatic" the term used to describe the engine cylinder and automatic transmission and processing process. 50's, automatic regulator and the development of classical control theory to automate access to a single variable automatic control system based partial automation stage. 60's, with the emergence of modern control theory and the wide application of computer, automatic control and information processing, and ensure that the production process automation into the optimal control and management of integrated automation stage. 70's, automation becomes the object of large-scale, complex projects and non-engineering systems, modern control theory involves many difficult problems. Research on these issues, to promote the automation of the theories, methods and means of innovation, ther...
