Abstract :
This paper explores dynamic modeling and design of a typical two stage metering poppet valve system. In particular, nonlinear and linear models of a forced feedback configuration are developed and parameters tuned through the use of root locus techniques. Typical steady state conditions as well as extreme high and low pressure drops are simulated in attempts to uncover instabilities and other possible undesirable performance characteristics of the valve. Finally the nonlinear model is used to produce Bode plots at various pressure drops in order to estimate the system bandwidth
