... for vibration suppression simulation and the numerical results indicate that the adaptive algorithm is effective in cases of multiple fluctuating frequencies and output saturation. Experiments were also conducted to test the performance of the adaptive method. Excitation with oscillating frequencies was applied...

...Bingbing Hu; Chang Guo; Jimei Wu; Jiahui Tang; Jialing Zhang; Yuan Wang As a weak signal processing method that utilizes noise enhanced fault signals, stochastic resonance (SR) is widely used in mechanical fault diagnosis. However, the classic bistable SR has a problem with output saturation, which...
