COMBINED SYSTEM WITH AN IMPLICIT STANDARD FOR A CLASS OF UNCERTAIN A PRIORI SINGLE-CHANNEL NON-AFFINE CONTROL PLANTS ON THE SET OF OPERATION STATES

Under the conditions of structural, functional and parametric uncertainty, the synthesis of algo-rithms of the combined control system for a class of single-channel non-affine plants with a step-by-step variable is carried outunder condition of limited external interference and measurement of only the controlled variable. Based on the hyperstability criterion, L-dissipativity conditions, the passification method andon the application of the implicit reference model and two correction filters in the control system, it is proved, that for the non-affine object studied on the set of operation states (caused by its arbitrary switching), it is possible to create a control law that ensures the achievement of the goal. The results of the simulation modeling showed considerably high efficiency of tracking the reference signal for a priori uncertain plants with non-affinity for control.
