Model Development and Analysis of the Dynamics of Pressure-Sensitive Paints

摘要: Two models for the dynamic behavior of pressure-sensitive paints are developed. The e rst two is a purely empirical approach to designing model and compensator. second presented encompasses physics process by which an unsteady pressure eld over paint layer affects causes intensity uorescence that uctuating in time. Within this model, different forms static calibration chosen. effect on system dynamics demonstrated.
