MONITOR UNIT FOR EXTREMAL CONTROLLER Russian patent published in 2013 - IPC G05B13/00 

FIELD: physics.

SUBSTANCE: disclosed is a monitor unit for a step extremal control which has an input adder, an adder in an adjustment channel, an input integrator, an integrator the adjustment channel, an input signal memory cell, an output signal memory cell, a signum relay, a relay element with a controlled dead zone, a multiplier, a timer with controlled pulse duration, a switch at the input of the input signal memory cell, a switch at the output of the input integrator and a switch at the input of the output signal memory cell. In order to determine the deviation sign of the controlled quantity at the interval of the k-th step, an estimate is used, which is obtained by integration in the input integrator of the difference, calculated in the input adder, between the current controlled quantity and its value recorded in the input signal memory cell at the end of the k-th step; the direction (sign) of the control action on the k-th step is calculated using the signum relay, which converts the signal at the output of the input integrator, the output signal memory cell in which the sign of the control action on the (k-1)-th step is recorded and a multiplier for signals from outputs of the signum relay and the output signal memory cell; and setup of operation with a specific control object on an optimum pulse duration and pulse ratio is carried out using the timer with controlled pulse duration and the relay element with a controlled dead zone.

EFFECT: high reliability of extremal control circuits.
