Abstract
A new mathematical model for the hydraulic servovalve employed in the axis servos of the DSS 14 70-m antenna is described. The model is based on a system of simultaneous nonlinear equations relating pressure and flow in the multiple orifices and internal flow paths of the valve. The model accounts for critical imperfections expected to affect valve performance such as overlap, radial leakage clearance, and rounded orifice edges attributed to mechanical wear. The model is structured for use with mathematical analysis software and execution on 80286-based microcomputers. It is expected to provide a new insight into the pressure and flow responses of the valve in the region of zero flow.
