Abstract
A simplified mathematical mode! is developed to study the dynamic behavior of an electro-pneumatic proportional valve for pressure control. The valve is capable of supplying a pressure that can reproduce an electrical signa! (electrical current intensity ). In addttion to parameters and independent variables, every differential equation constituting the model contains a coefficient which includes several geometrical parameters and some parameters related to flow through the valve. Thls coefficient may be determined by comparing results from experiments and simulated tests. The application of this method has given simulation-derived results that sufflciently approximate the experimental results of practlcal applications.Pubblicazioni consigliate
