Question:
A hydraulic servomechanism with mechanical feedback is shown in Figure P2.21 [18]. The power piston has an area equal to A. When the valve is moved a small amount z, the oil will flow through to the cylinder at a rate p z, where p is the port coefficient. The input oil pressure is assumed to be constant. From the geometry, we find that
(a) Determine the closed-loop signal-flow graph or block diagram for this mechanical system,
(b) Obtain the closed-loop transfer function Y(s)/X(s).
