Cybernetics action

Cybernetic Action and the Principle of Least Cybernetic Action... 

Even better, a well-designed PAT system has built in the capability of self-correcting many kinds of problems. This cybernetic capability—much like the thermostat on a home heating system—senses the appropriate press pressure level and self-corrects if it exceeds norms. The cybernetic capability is more certain and more rapid than the notification of a human to take corrective actions.

Safety Actions from a Cybernetic Point of View. From the point of view of cybernetics, the disturbing influences of a system are considered potential sources of endangerment. Their time cannot be controlled nor individually predicted. They pose a danger to the system s stability. A system, in turn, has two possibilities of absorbing the effects of such disturbances compensation by feedback and buffering or shielding, respectively. In real systems, combinations of the two are often applied. 

The cybernetic model of system control is based on the assumption that one can achieve at best only some approximation of what he aims at. Therefore, salvation lies in rapid detection of error and adjustment to correct for that error. this cybernetic model... makes it natural to think of the second-order consequences of one s actions. Error is not a rare phenomenon that occurs because of bad planning and inept control. It is the natural and inevitable outcome of all purposive action. ...
