Cybernetical physicsとは 意味・読み方・使い方

Cybernetical physics is a scientific area on the border of Cybernetics and Physics, studying physical systems by cybernetics methods. Cybernetics methods are understood as methods developed within control theory, information theory, systems theory and related areas: control design, estimation, identification, optimization, pattern recognition, signal processing, image processing, etc. Physical systems are also understood in a broad sense: either lifeless or living nature or of artificial (engineering) origin, having reasonably understood dynamics and models suited for posing cybernetical problems. Research objective in cybernetical physics is formulated as analyzing a class of possible system properties changes under external (controlling) actions from a certain class. An auxiliary goal is design of controlling actions required to achieve prespecified property change. Among typical control action classes are functions, constant in time (bifurcation analysis, optimization), functions, depending only on time (vibration mechanics, spectroscopic studies, program control), functions which value depends on measurement results at the same time or previous instants. The last class is of special interest since it corresponds to system analysis by means of external feedback (feedback control).
