Abstract
The paper presents a model for a four-way servovalve which is based on nonlinear modelling of valves’ leakage behaviour. The model is identified according to measured flow rate at valve ports and pressure gain curve. The model can take into account some unsymmetry of the valve.
The model is verified in the case of a commercial servovalve.
