ADAPTIVE CONTROL OF AN OUTPUT OBJECT UNDER THE CONDITION OF SATURATION OF THE CONTROL SIGNALIN THE SYSTEM WITH FAST OBSERVER

This article deals with an adaptive control system of a single channel object with a relative degree ρ = n – m> 1, and saturation nonlinearity at the input. We used the observation circuit to generate estimates of state variables of the control object in the system with two reference models, under dynamic correction of the self-adjustment process of the adaptive controller coefficients. Synthesis of the adaptive control system is based on the application of hyperstability criterion, taking into account a fast stationary observer and a clear standard with two outputs, as well as dynamic switch in the circuit adaptation.
