本文将α 稳定噪声与单稳随机共振系统相结合，研究了乘性和加性α 稳定噪声环境下的过阻尼单稳随机共振现象，探究了α 稳定噪声特征指数α（0 α ≤ 2）、对称参数β（-1 ≤ β ≤ 1），单稳系统参数a及乘性α 稳定噪声放大系数D对共振输出效应的作用规律. 研究结果表明，在不同分布的α 稳定噪声环境下，在一定范围内通过调节a或D均可诱导随机共振来实现单个或多个高、低频微弱信号的检测，且a和D分别存在一个最优值可使系统产生最佳的随机共振效应；不同α 或β 均可对系统共振输出效应产生规律性的影响，且α 或β在高、低频微弱信号检测中的作用规律相同；在研究α 稳定噪声环境下单、多频单稳随机共振现象时所得结论是相同的. 本研究结果可为实现α 稳定噪声环境下单稳随机共振系统参数的自适应调节奠定基础.In this paper we combine α stable noise with a monostable stochastic resonance (SR) system to investigate the overdamped monostable SR phenomenon with multiplicative and additive α stable noise, and explore the action laws of the stability index α (0 α ≤ 2) and skewness parameter β (-1 ≤ β ≤ 1) of the α stable noise, the monostable system parameter a, and the amplification factor D of the multiplicative α stable noise against the resonance output effect. Results show that for different distributions of α stable noise, the single or multiple low-and high-frequency weak signals detection can be realized by adjusting the parameter a or D within a certain range. For a or D, respectively, there is an optimal value which can make the system produce the best SR effect. Different α or β can regularly change the system resonance output effect. Moreover, when α or β is given different values, the evolution laws in the monostable SR system excited by low-and high-frequency weak signals are the same. The conclusions drawn for the study of single-and multi-frequency monostable SR with α stable noise are also the same. These results will be the foundation for realizing the adaptive parameter adjustment in the monostable SR system with α stable noise.
