Transient Response of First Stage of Electrohydraulic Servovalve

Transient response of the exit pressures of first stage of electrohydraulic servovalve

The electrohydraulic servovalves are mostly multi-stage. They incorporate, mostly, a first stage which serves to convert the command current into a proportional pressure difference. For more details about the steady state and transient response calculation, please refer to my book:
