ADAPTIVE THREE-POSITION REGULATOR Russian patent published in 2011 - IPC G05B11/18 

FIELD: physics.

SUBSTANCE: device has two inverters and two dead zone setting device, a dual-threshold comparator, a bidirectional counter, a delay element, an AND element, an OR element, as well as an ultralow frequency generator with discretely varying period of output pulses, a constant pulse generator, a logical controller, a decoder and light-emitting diodes connected to each of the outputs of the decoder, the outputs of which are connected to the common bus (housing). Outputs of the decoder are connected to outputs of the bidirectional counter and inputs of the logical controller, whose outputs are connected to control inputs of closing contacts K₁-K₄ of the ultralow frequency generator with discretely varying period of output pulses, whose output is connected to the second input of the AND element. In the regulator, the pulse ratio of medium pulsed signals is varied by varying the pulse repetition period while the pulse for pulse for switching on the actuator is constant.

EFFECT: improved quality of controlling process value of the object and low power consumed by the object.
