METHOD OF ADAPTIVE CONTROL BY ELECTROHYDRAULIC SERVOSYSTEM AND ELECTROHYDRAULIC SERVOSYSTEM

摘要

FIELD: hydroautomatics. SUBSTANCE: in compliance with method of adaptive control by electrohydraulic servosystem there is created pressure differential across hydraulic prime mover by means of electrohydraulic torque amplifier by working instructions of numerical program control device. Outlet rod of hydraulic primer mover acts along one direction on one side on pusher resting against spreading members and on the other side - on travel transducer of pusher forming signals in the form of pulses received by numerical program control device. Moment of touch by spreading members of internal surface of object is recorded and mismatch value is controlled in servosystem with the aid of operators of conditional transition placed in sequence which record moment of touch and transmit control to proper operator of working instructions of numerical program control. Spreading members are brought to interaction in advance till they touch standard ring installed additionally uniaxially to mentioned direction of action on travel transducer which signal is recorded at moment of touch. EFFECT: increased reliability of control. 4 cl, 2 dwg
