ALGORITHMS OF ADAPTIVE SYSTEM FOR PLANT WITH SATURATION AND CONTROL DELAY

The article considers the way of constructing adaptive control system by uncertain singlechannel object with control delay without measuring its state variables in the circuit with filtercorrector and modified standard predictor when under saturation or nonlinearity (non-affinity) of a control signal the plant is subject to influence of uncontrollable, but limited indignations. In order to eliminate saturation effect either totally or partially on control system functioning in regulator structure there should be applied a dynamic switch providing set scaling of amplification factors in a contour of a regulator self-adjustment.

Keywords: plant with control saturation and delay, modified standard predictor, filtercorrector, dynamic switch, aprioristic parametric uncertainty, structural indignation, adaptive regulator, hyperstability, L-dissipativity
