METHOD FOR ADAPTIVE PID LAW-BASED CONTROL AND SYSTEM FOR REALISING SAID METHOD Russian patent published in 2014 - IPC G05B13/00 

FIELD: physics; control.

SUBSTANCE: invention relates to automated control of complex information devices using PID control laws, and can be used in radio systems with chaotic dynamic realisation of their target functions in intense information perturbation conditions. The method involves establishing conformity between acceptable criticality levels of deviations of configuration parameters of the controlled system and the criticality level of their deviations; using values of a decision matrix to calculate the error of deviations of values of the configuration parameters of the controlled system and checking their conformity with the acceptable criticality levels of deviations of the configuration parameters of the controlled system; in case of conformity, storing previous values of the configuration parameters of the controlled system and re-factoring the initial content of a plurality of values of the decision matrix, and in case of non-conformity, storing that event and calculating the error of deviations of values of the configuration parameters of the controlled system and assigning a control action for the controlled system based on selection of values from the decision matrix; in case of detection of missing and/or incorrect given values of configuration parameters of the controlled system, re-factoring content of a plurality of values of the decision matrix on each of the configuration parameters of the controlled system for the given operating conditions of the controlled system by adding the detected missing values and/or changes in incorrect values of the decision matrix; storing previous values of the configuration parameters of the controlled system, assigning a control action to the controlled system and re-factoring content of a plurality of values of the decision matrix by replacing previous values of the configuration parameters of the controlled system with current values of the configuration parameters of the controlled system. The system comprises switching matrices of inputs and outputs (1, 2) of the decision device (3), a proportional unit (4), functional logic controller (9), an actuating unit (11), a controlled object (12) and an integrating-differentiating unit (10), having K integrating-differentiating clusters (7₁…7_k), each having one of the K integrating units (5₁…5_k) and one of the K differentiating units (6₁…6_k) with own normalising factors.

EFFECT: improved dynamics of control processes and broader functional capabilities.
