Abstract

Abstract

First, the pressure transducer is calibrated using the shock tube. Second, the mathematical model of the pressure transducer is established through the system identification with Generalized Least Square Iterative Method with Special Whitening Filter. According to the model the dynamic characteristics can be obtained. Finally, the dynamic characteristics compensation method based on the zero pole cancellation method is proposed and applied to data processing. Practical application shows that data processing method based on dynamic compensation can improve the dynamic characteristics of the sensor and the accuracy of the test data.
