Abstract:

The dynamic response behavior is one of the most important factors of an anti g valve suit system. A linear model which includes four pole, four zero and one delay unit was developed in this paper to describe the dynamic response behavior of the valve g suit system. The parameters in the model were determined through a system identification method, and the agreement between model prediction and experimental result was satisfactory. The influences of system structural parameters such as source pressure, suit volume and valve angle were also discussed.
