摘要
Abstract
In this paper,a method for adjusting parameters of Time-Difference Fluxgate system is proposed, where feedback module is applied. Based on the observation of time-difference output of simulated Langevin equation,research is conducted on the influence of both linear feedback and cubic feedback on system parameters and stochastic resonance effect, and conclusions that linear feedback lowers coerrivity.and cubic feedback adjusts optimal stochastic resonance noise are drawn. Numerical simulations of the models with MATLAB shows that addition of feedback module makes it more convenient for the Time-Difference Fluxgate system to adjust its internal parameters and control the stochastic resonance effect, which improves the performance of the system considerably. Compared with no feedback module,the sensitivity is enhanced by 50% .关键词
