RELAY CONTROLLER WITH VARIABLE STRUCTURE Russian patent published in 2017 - IPC G05B11/16 

FIELD: machine building.

SUBSTANCE: invention relates to automatic regulators. Relay control with variable structure comprises deviations detecting unit, adder, relay unit, switching element, null device, extreme values indicator. Indicator input is connected to controller first input, deviations detecting unit first input and null device second inverting input, and outputs are connected to relay unit inputs. Relay unit output is connected to adder first input, adder second input is connected to deviations detecting unit data output, and output is connected to switching element first input. Switching element control input is connected to deviations detection unit control output, which second input is connected to controller second input. Regulator includes second adder, which first input is connected to relay unit output, second input is to controller first input and output is to switching element second input, which output is connected to null device first input. Null device output is connected to controller output. Device is relay controller with negative variable hysteresis and dead zone, operating on “on-off” principle.

EFFECT: technical result consists in improvement of control accuracy.
