Any control process, to be used in a cybernetic system, implies continuous information exchange between the controlled object (a ma- chine or a human muscle) and the control unit (an automatic regulator or the brain of a living organism). The control process represented on the scheme below involves the transmission, accumulation, storage and processing of information about the controlled object. The laws governing control processes are based on such fundamental concepts as feed-forward and feedback. The controlled object receives information from the control through the feed-forward and modifies its behavior. The information transmitting process about the effects or results of the control operations is achieved through feedback.
