ADAPTIVE SYSTEM FOR CONTROLLING AND STABILISING PHYSICAL QUANTITIES Russian patent published in 2012 - IPC G05B13/02 

FIELD: physics.

SUBSTANCE: adaptive system with feedback has series-connected object, subtractor and controlled amplifier whose control input is connected to the output of an adder. The apparatus also includes the following, connected in series between the output of the subtractor and the input of the adder: an error analyser, a synchronous detector, a nonlinear element, an integrator and a coefficient regulator, as well as a generator whose output is connected to the second inputs of the synchronous detector and the adder, wherein the output of the controlled amplifier is connected to the input of the object and the input of the system is the positive input of the subtractor and the output is the output of the object.

EFFECT: high efficiency of self-adjustment and achieving high accuracy of the adaptive system in order to increase accuracy and speed of operation when parameters of the object change.
