Abstract: In the process of shock wave testing, the test signal is distorted by the limited bandwidth and low resonant frequency of pressure sensor. In order to solve this problem, a pressure sensor dynamic compensation method which is based on fireworks algorithm is presented. And the fitness function for the dynamic compensation is improved to increase the dynamic performance. The transfer function of dynamic compensation of pressure sensor is obtained from the test data of shock tube. The rise time of step pressure signal can be improved to 15.0 μs, and the overshoot is reduced to 8.27% after dynamic compensation by the proposed method. In the actual muzzle shock wave test, the dynamic compensation method can suppress the resonant frequency effectively, and make the pressure sensor test system achieve a better dynamic performance.
