Servo valve built from bond graph technology
The servo valve model described here has a signal input, the
position of the tongue, x, and two bondgraphic outputs: the
two load flows, qL1 and qL2.
The bondgraphic interface is designed such that the servo valve can
be directly connected to the hydraulic motor without either a set
of bonds or a set of junctions in between.
The two chambers of the servo valve are at the pressures
p1 and p2, respectively.
The four valve flows, q1,
q2, q3, and
q4, are assumed to be turbulent flows. The valve
flows are modulated by the tongue position. The modulation of the
four hydraulic conductors representing the turbulent flows is
computed by the Modulator block.
