| Abstract: | The interaction of a coupled system and an external force is analyzed.The method of controlling stochastic energetic resonance is proposed from the viewpoint of work done and energy.According to the stochastic dynamics described by two-dimensional coupled Langevin equation,the thermodynamic relations of coupled systems based on single stochastic trajectories are estab-lished using microcosmic dynamics and macroscopic thermodynamic methods.By adjusting the periodic external force acting upon the control syst... |
