ADAPTIVE CONTROL SYSTEM WITH DOUBLE-STAGE IDENTIFIER AND WITH IMPLICIT PATTERN MODEL Russian patent published in 2004 - IPC

FIELD: systems for automatic control of dynamic objects with non-controlled disturbances, unknown variable parameters and time delay in control circuit and also having natural frequency spectrum range in control circuit exceeding spectrum range of working frequencies of object itself.

SUBSTANCE: system is realized when relation of working frequencies of object and spectrum of control signals is known. In system current process of identification is carried out by two stages. At first stage evaluated parameters of matrix of control effectiveness of object and time delay of control process are calculated. At second stage parameters of matrix of specific dynamic properties of object are calculated. System includes adder, first and second regulators, low frequency filter, controlled object, unit for performing second stage of current identification process, unit for tuning regulators, unit for performing first stage of current identification, band filter unit, boosting unit.

EFFECT: possibility for achieving preset quality of control process in closed system for given type of objects.
