Adaptive Stochastic Resonance Based on Particle Swarm Optimization with Application in Parameters Optimization
The parameters of traditional stochastic resonance (SR) are selected manually,which heavily depends on experience.Therefore,a new method of parameters optimization,that is the so-called adaptive SR based on particle swarm optimization (PSO),is introduced to adaptively select the optimal parameters of SR in this paper.The output signal-to-noise ratio (SNR) of SR is determined as the fitness function of PSO,and by utilizing the ability of global and concurrent search of PSO,the optimal structure parameters of bistable system is solved adaptively,and then the bistable system can obtain the best resonance state automatically.The simulation results show that the adaptive method,which proposed in this paper,is scientifically practical,and fast to detect the weak signal under strong background noise.
