Adaptive Repetitive Control of Nonlinear Undefined Plant with Input Saturation and Delay

In the article it is proposed an adaptive control algorithm for a class of nonlinear T-periodic dynamic plants with structural-parametric uncertainty, saturation of the input signal, and delay. The plant also has a permanent external perturbation which is cyclical. As methods for the adaptive repetitive control system synthesis the hyperstability criterion, L-dissipativity conditions, high-speed correction filter, implicit reference model and generator for periodic signals are used. The performance of the proposed adaptive repetitive control system is shown at the stage of simulation. Obtained results may be useful for designing of adaptive control systems for T-periodic plants with various types of delays and permanent cyclical perturbations.
