A new fluctuation assessment method for the step response signals of pressure sensors

摘要: Abstract In dynamic measurement of a step pressure, the response signals from sensor are usually influenced by mechanical vibrations. It is difficult to accurately describe characteristics pressures directly using collected therefore leading unsatisfactory results. this paper, new method proposed quantitatively assess fluctuation signals. Firstly, signal partitioned into subsequences, and series reconstructed sequences obtained each subsequence introducing delay embedding dimension. Then, an evaluation indicator named measure defined for as average specific fuzzy operator any two sequences. Finally, composite calculated taking ordered weighted mean measures these subsequences. Measurement experiments with different sensors vibration conditions carried out validate performance our method. The results show that works well in quantifying Comparative also demonstrate superiority over existing approaches.
