摘要
FIELD: automatic control systems for test machines with electrohydraulic servo drive. SUBSTANCE: device has two channels with digital-to-analog converters and feedback sensors whose outputs are connected to inputs of summing amplifiers and with switching units affording connection of this or that control variable to actuating element of controlled entity; outputs of summing amplifiers in both channels are connected to inputs of switching units and to one of inputs of two comparators inserted in each of channels whose other inputs are interconnected and connected to outputs of switching units and to input of controlled entity actuating element; switching units of one channel have breaking contact and those of other channel, making contact. EFFECT: enhanced precision of shock-free transfer from one control variable to other. 1 cl, 1 dwg
