METHOD FOR MAKING THREE-POSITION REGULATOR Russian patent published in 2003 - IPC

FIELD: automatic control devices, namely three-position regulators with adaptive mean position, possibly used for automatization of industrial objects and domestic devices in order to regulate their technological parameters. SUBSTANCE: contact-free connection of functional readjustment unit is achieved due to connecting it with outlet of three-position regulator with fixed positions in parallel connecting it with amplifying unit having gain K equal to 2 or more and further applying summed signal of said two parallel circuits to saturation type circuit with gain equal to 1 and with values of saturation signals equal to values of boundary positions of initial three-position regulator relative to its mean position. EFFECT: simplified conversion of usual three-position regulator with fixed positions to three position regulator with adaptive mean position, enhanced operational reliability of regulator. 3 cl, 1 dwg
