Control strategy research for super-Gaussian random vibration test
Based on the study of control theory of the super-Gaussian random vibration test, The super-Gaussian random signal generation principle is studied, what is more, drive signal required for the control system is generated by use of Poisson process and filtering theory. The simulation and experiment tells that the method to generate super-Gaussian random signal is correct, meanwhile, based on the proposed super-Gaussian random vibration control strategy, the high accuracy of output power spectrum and kurtosis can be realized, which satisfies the requirement in practical. At the end, super-Gaussian random vibration control system is applied into the Highly Accelerated life Testing(HALT) in terms of fans, the comparison results indicate that supe
