两个双稳系统经非线性耦合而成为多稳态系统,该耦合系统与单一双稳系统相比具有较高的理论研究和实际应用价值.解析地分析了耦合系统在含噪弱周期信号作用下的响应特性,给出了耦合系数和双稳系统参数对随机共振的影响,表明耦合系统的随机共振是在带状的双势阱作用下产生的,还构建了反馈耦合控制原理框图.这为在双稳类系统中人为地产生随机共振或使共振效应更加强烈即随机共振的控制及其应用提供了可靠的理论依据.数值仿真结果与理论分析完全符合.
The two bistable systems are non-linearly coupled to form a multi-stable system, which has a higher theoretical and practical value than a single bistable system.Analysis of the effect of the coupling system on signal with weak period The influence of the coupling coefficient and bistable system parameters on the stochastic resonance is given. It is shown that the stochastic resonance of the coupling system is generated by the double-well ribbon shape, and the block diagram of feedback coupling control is also constructed. It provides a reliable theoretical basis for the control and its application of stochastic resonance in man-made bistable system or making the resonance effect stronger, ie stochastic resonance.The numerical simulation results are in good agreement with the theoretical analysis.
