REPETITIVE ROBUST CONTROL SYSTEM FOR A CLASS OF NONLINEAR UNDEFINED PLANTS WITH INPUT SATURATION
The paper describes the process of synthesizing algorithms for a periodic robust control system for a nonlinear single-channel plants with saturation of the control input. The hyperstability criterion is used under conditions of structural-functional-parametric uncertainty. The design of the robust control law at parametric, functional, structural uncertainties and permanent noise relies on the hyperstability criterion and the conditions of L-dissipativity. The simulation is used to examine the quality of the proposed robust control system.
