GEAR MODELLING N-POSITION DIGITAL ELECTROHYDRAULIC DRIVE WITH MAJORIZATION OF CONTROLLING SIGNALS Russian patent published in 1997 - IPC

FIELD: control systems, specifically, for modelling the electrohydraulic mechanisms, and used in half-nature modelling in digital systems with real control loop. SUBSTANCE: gear comprises model of windings of electromagnetic mechanism and model of hydraulic drive incorporating code-to-analog converter, integrator, former of controlling signal, units converting bipolar pulses to unipolar code in agreement with number of windings of electromagnetic mechanism, units testing input signal, code correction unit, indicator and matching unit. Structure of gear makes it possible to carry out approval tests of real equipment controlling drives under conditions close to real with insufficient additional expenses simulating processes going on in control circuits, to develop closed control circuits by standard programs. Gear has high correspondence by input and output to read drive and considerable resources. EFFECT: reduced expenditures and time for manufacturing and adjustment. 1 dwg
