将双稳系统的输出反馈到输入端再作用于系统,提出了采用反馈来控制随机共振的方法.以典型双稳系统为对象,并以信噪比和功率谱放大率作为度量随机共振效应的可观察变量,分别研究了采用线性或非线性反馈函数所产生的随机共振现象.理论分析和数值仿真结果表明随机共振是可控制的.该方法特别适用于系统参数固定或难以改变的系统. The output of the bistable system is fed back to the input end and then applied to the system, a method of using feedback to control the stochastic resonance is proposed.The typical bistable system is taken as an object, and the signal-to-noise ratio and power spectral magnification are taken as the measurement of stochastic resonance Observable variables and stochastic resonance phenomenon by using linear or nonlinear feedback function respectively.The theoretical analysis and numerical simulation results show that stochastic resonance is controllable.This method is especially suitable for systems with fixed or difficult parameters.
