1. The semantic field of self-regulation
Self-regulation (or automatic regulation) is used in systems theory and cybernetics in the sense of homeostasis (→feedback), namely the capacity of a system to maintain itself in a balanced situation. In this sense the term is very commonly used in psychology, though not in the meaning of "automatic regulation", but as "regulation of the self", also named self-control (i.e. the ability to control one´s emotions, desires or actions by one's own will). Since automatic is used in a sense of acting without volition or conscious control, there is a certain semantic opposition between the psychological meaning of "self-regulation" or "self-control", on one hand, and "automatic regulation" or "automatic control", on the other hand.
Automatic regulation, also used in the sense of an autonomous maintenance of a balanced situation, is mainly found in the field of electronic systems and control engineering (→control theory). 2. Brief history of automatic regulation
The concept of automated machines goes back to ancient times, related to myths of living mechanical beings. Automata, or machines like people, appeared in clocks of medieval churches, being 18th century watchmakers well-known for their smart mechanical creatures.
However, there was a lack of theoretical and mathematical development behind all these inventions. The first work of what can be called a classical control theory is to be found in a significant work concerning the centrifugal gobernor of Boulton and Watt designed in 1788 (Rumford 1798). This device consisted of two metal balls attached to the drive shaft of a steam engine and connected to a valve regulating the flow of steam. As the speed of the steam engine is increased, the balls are moving out of the shaft because of centrifugal force, thereby closing the valve. This caused a decline in the flow of steam to the engine and therefore the speed will be reduced. 3. Industrial Automation
The feedback control, the development of specialized tools and distribution of work into smaller tasks that workers or machines might handle, were essential ingredients in the automation of industry in the eighteenth century. As technology improved, specialized machines were developed for tasks such as putting caps on bottles or pour liquid into molds for rubber tires. However, none of these machines have the versatility and efficiency of the human arm and could not reach distant objects and place them in the required position.
An automated manufacturing system is designed to use the capacity of machines to perform certain tasks previously tackled by humans, and to control the sequence of operations without human intervention. The term automation has also been used to describe non-manufacturing systems in which programmed or automated devices can operate independently or semi-independently of human control. In communications, aviation and astronautics, devices such as automatic telephone switching equipment, autopilots, and automated systems guidance and control are used to perform different tasks faster or better than human beings. 4. Social regulation of automation
Following an uncritical dominant concept of social progress, automation is considered as one of their pillars, increasing productivity and reducing human drudgery, therefore improving general welfare. Nevertheless, the political, societal and anthropological problems arisen with industrial automation -as early warned by Norbert Wiener (1989)- must be considered in order to evaluate and steer the paths of automation. This critical appraisal might be conceived as a means to achieve a social self-regulation (in the sense stressed above) to this concern. However, as Noble (1993) argues in his Automation Madness, such a critical stance has been systematically evaded as well as encapsulated in technological ideology (Habermas 1970). According to Noble analysis, the adoption of automation did not really account for economical benefits, but for military, power and class interests.
Going beyond industrial automation, new information technologies have been posed as the automation of intellectual work (Diani 1996). New social problems arisen from this perspective should also be tackled in a wide critical assessment, reflection and decision-making on automation of any kind (Chollet and Rivière 2010). Both ethics and critical theory has been posed as stages for these social endeavours ( References

The concept of automated machines goes back to ancient times. Automata, or machines like people, and clocks appeared in medieval churches and 8th century watchmakers were well known for their smart mechanical discoveries.
Some of the first robots utilized feedback mechanisms to reduce errors, mechanisms that are still used nowadays. An example of feedback control is a liquid tank which uses a float to control the water level. When the water falls below a desired level, the float comes down, a valve opens and allows more water to enter in the tank. When the water goes up, the float rises too, and at a certain height the valve is closed and cut off the water. The first real feedback system was the Watt regulator, invented in 1788 by the British engineer James Watt. This device consisted of two metal balls attached to the drive shaft of a steam engine and connected to a valve regulating the flow of steam. As the speed of the steam engine is increased, the balls are moving out of the shaft because of centrifugal force, thereby closing the valve. This caused a decline in the flow of steam to the engine and therefore the speed will be reduced. The feedback control, the development of specialized tools and distribution of work into smaller tasks that workers or machines might handle, were essential ingredients in the industry automation in the eighteenth century. As technology improved, specialized machines were developed for tasks such as putting caps on bottles or pour liquid into molds for rubber tires. However, none of these machines have the versatility and efficiency of the human arm and could not reach distant objects and place them in the required position.

Self-regulation (or automatic regulation) used in systems theory and cybernetics in the sense of homeostasis (→feedback), i.e., the capacity of a system to maintain itself in a equilibrium condition.
In this sense, the term is commonly used in psychology, though not as an "automatic regulation", but as "self-regulation ", also named self-control, i.e. the ability to control one´s emotions, desires or actions by one's own will. Since automatic is used in a sense of acting without volition or concious control, there is a certain semantic confusion between the psychological meaning of "self-regulation" or "self-control", on the one hand, and "automatic regulation" or "automatic control", on the other hand.
Automatic regulation -used in the same sense- is mainly found within the field of electronic systems and control engineering (→control theory). |
