摘要: The paper presents a numerical method of realizing stochastic resonance (SR) by tuning system parameters. Firstly, simple and effective evaluating the response speed λ1 is introduced. Then parameter-induced SR problem can be reduced to parameter optimization under condition = const. To solve this problem, we put forward following techniques: (i) compensate deviation from prescribed at each step, (ii) take curve length increment on plane as step size in searching maximal signal-to-noise ratio (SNR) gain. Finally, simulation confirms effectiveness method.
