Online Dynamic Compensation of Pressure Sensor

Abstract:

An online dynamic compensation of the pressure sensor based on simultaneous identification method of model order and parameter is proposed to identify the model of pressure sensor and set digital compensation links for the pressure sensor. While simulating, the compensation links can broaden the frequency band and improve the dynamic process of the pressure sensor. This article describes the realization of the digital dynamic compensation with DSP processor and the process of the experimental verification. The results show that the simultaneous identification method can be used in determination of model and digital compensation links for pressure sensor effectively. And DSP measurement device can complete online dynamic compensation effectively.
