微弱信号检测在故障的早期诊断中具有重要意义。随机共振能够利用噪声放大微弱有用信号,对信号检测起到协助作用。利用智能算法自适应地调整优化随机共振系统的参数,使系统达到最好的随机共振效果。为弥补单一智能算法的不足,将多种智能算法相结合并应用到自适应随机共振系统中是目前随机共振故障诊断研究的发展方向。
Weak signal detection in the early diagnosis of failure is of great significance. Stochastic resonance can amplify a weakly useful signal with noise and assist in signal detection. Using intelligent algorithm to adaptively adjust and optimize the parameters of stochastic resonance system, the system achieves the best stochastic resonance effect. To make up for the lack of a single intelligent algorithm, the combination of a variety of intelligent algorithms and applied to adaptive stochastic resonance system is the development direction of stochastic resonance fault diagnosis research.
