CYBERNETICAL PHYSICS: BLEND OF PHYSICS AND CONTROL
PhysCon 2003, Plenary Talk.
In the talk some key results and problems of cybernetical physics - studying
physical systems by cybernetical means, will be discussed. The subject and methodology of
cybernetical physics will be outlined. Transformation laws for Hamiltonian and dissipative
systems under bounded control will be presented. Application to feedback resonance
phenomenon in nonlinear oscillators and its consequences for physics (controlled Kapitsa
pendulum, feedback escape from potential wells, controlled dissociation of diatomic
molecules) will be discussed. A number of other real and potential applications in science and
technology will be surveyed. The results to be presented extend the previous ones [1-4].
